CHAPTER 8

"Third Conjugation (duco): Present Infinitive, Present and Future Indicative, Present Imperative Active"

PRESENT INFINITIVE AND PRESENT TENSE

You remember that Latin verbs are divided into groups called "conjugations", and the conjugations are distinguished from one another by their thematic vowels. The thematic vowel of the first conjugation is "-a-"; the thematic vowel of the second is "-e-". You can tell what the stem vowel (its thematic vowel) of a verb is -- and thereby its conjugation -- by dropping the "-re" ending from the infinitive, which is given to you in the dictionary.

           laudo  laudare       stem: lauda-   1st conjugation

           moneo  monere        stem: mone-    2nd conjugation

Now look at the dictionary entry for the verb "to lead" in Latin: "duco, ducere". Simply by looking at the first entry, you might think that this verb is going to be a first conjugation verb -- it looks like "laudo". But the next entry looks something like a second. Find the stem: it's duce-. You have to look closely, but the "-e-" of the stem is short. This is the characteristic vowel of the third conjugation: short "-e-".

Even if you're not watching the long marks, you can still tell a second conjugation verb in the dictionary from a third. The first entry for a second conjugation verb will always end in "-eo", and then the second entry will end "-ere". The first dictionary entry of a third conjugation ends simply with "-o" and then the second entry is "-ere". So if the first entry of a verb looks like a first conjugation verb in the first person singular and if the infinitive looks like a second conjugation verb, then you have a third conjugation verb. Identify the conjugations of the following verbs:


  ENTRY              CONJUGATION   ENTRY                CONJUGATION



  doceo, docere      __________    audeo, audere          __________



  amo, amare         __________    tolero, tolerare       __________



  duco, ducere       __________    valeo, valere          __________



  scribo, scribere   __________    ago, agere             __________



We'll use "duco" as our example (paradigm) of third conjugation verbs. Now let's see about conjugating a third conjugation verb in the present tense. You remember the formula for all verbs in Latin in the present tense: it's just the stem plus the personal endings "-o", "-s", "-t", etc. Fill out the following table, except for the conjugated form.

PRESENT TENSE OF "duco, ducere"


           STEM   +     PERSONAL ENDINGS    =      CONJUGATED FORM



1st      _________       __________             ____________________



2nd      _________       __________             ____________________



3rd      _________       __________             ____________________





1st      _________       __________             ____________________



2nd      _________       __________             ____________________



3rd      _________       __________             ____________________

What we need to know is what happens to the stem vowel when you start attaching the personal endings. In the first and second declensions this presented no problem, because the stem vowels are long and strongly pronounced. But short vowels always cause difficulties in languages and are subject to changes. You already have experience with what happens to the short "-e-" before personal endings. Do you remember how you form the future tense of first and second conjugation verbs? You insert the tense sign "-b-" in between the stem and the personal endings. And then the short "-e-" changes:

                laudabo         -       laudabo ("-e-" disappears)

                laudabs         -       laudabis

                laudabt         -       laudabit



                laudabmus       -       laudabimus

                laudabtis       -       laudabitis

                laudabnt        -       laudabunt

This is what happens to short "-e-" before the personal endings. In third conjugation verb, then, what is going to happen to the short "-e-" of its stem? Right. It's going to undergo precisely the same changes. Now go back to the table and fill out the conjugated forms of "duco". (Check the answers in Wheelock, p. 35.)

FUTURE TENSE

Third conjugation verbs form the future tense in a way entirely different from that of the first and second conjugation. First and second conjugation verbs insert a tense sign -- "-be-" between the stem and the personal endings. Third conjugation verbs do two things:
  1. For the first person singular, they replace the stem vowel with an "-a-" and use the alternate personal ending "-m" -- instead of the more regular "-o".
  2. For all the other forms, they lengthen the short "-e-" of the stem to long "-e-". Since the "-e-" is now long, it no longer goes through any of the changes it went through in the present tense. It simply stays "-e-". (Except of course where long vowels normally become short: before "-t", and "-nt".)
Fill out the future tense of the verb "duco".

      STEM   +  TENSE SIGN   +  PERS. END.  =   CONJUGATED FORMS



1st    duc      __________      __________       _______________



2nd   _____     __________      __________       _______________



3rd   _____     __________      __________       _______________





1st   _____     __________      __________       _______________



2nd   _____     __________      __________       _______________



3rd   _____     __________      __________       _______________

FUTURE OF THIRD CONJUGATION VS. PRESENT OF SECOND CONJUGATION

The way a third conjugation verb forms its future presents an interesting problem. Write out the present tense of the second conjugation verb "moneo, monere", and next to it write out the future of the third conjugation verb "mitto, mittere" (to send).

                        moneo           mitto



                       PRESENT         FUTURE



                1st  __________      __________



                2nd  __________      __________



                3rd  __________      __________





                1st  __________      __________



                2nd  __________      __________



                3rd  __________      __________

As you can see, except for the first person singular, the endings of both these verbs look the same: the personal endings in both these verbs are preceded by an "-e-". The present tense of a second conjugation verb almost always looks like the future tense of a third conjugation verb, and this could cause you some problems when you're reading and translating. But not if you keep your wits about you.

Suppose that you see a form like this in a text you're reading: "legent". What do you do with it? First you recognize the "-nt" as an ending that's attached to verbs, so the word you're looking at is a verb. You want to look this verb up in the dictionary, so you must simplify it to its basic form, which is the first person singular. You remember that a verb is conjugated by adding personal ending, so to reduce this form, you drop of the "-nt". This leaves you with "lege-".

Now the next thing you have to consider is the "-e-": is it the stem vowel of a second conjugation verb, or is it the lengthened "-e-" of a third conjugation verb as the tense sign for the future? That is, is this a present tense form of a second conjugation verb (stem + personal endings), or is it a future of a third (stem + lengthened "-e-" + personal endings). What do you do next to find out? You've gone as far as you can with you preliminary analysis of the form. Now you have to proceed provisionally.

Suppose that the verb is a second conjugation, what will the dictionary entry look like? The first entry is the first person singular, the second is the infinitive, so, if this is a second conjugation verb, the entry will be "legeo, legere". Right? Because all second conjugation verbs end in "-eo" in the first person singular. So you've reduced the conjugated form "legent" to a form you can look up.

The next step is to look it up -- but look for exactly what you've supposed the form to be. Look for both "legeo", and "legere". Look it up. You didn't find it, did you? But if your analysis was correct, "legeo" must be there. But it's not. What does that tell you? It tells you that "legent" is not a form of a second conjugation verb. (If it were, you would have found "legeo" in the dictionary, but you didn't.) Go back to the other possibility: "legent" could be the future of a third conjugation verb, where the "-e-" is the sign of the future. So if this is correct, what will the dictionary entry be? It'll be "lego, legere". Check it out. This time you found what you were looking for: "lego" means "to read". So how do you translate "legent?"


                   leg-        -e-       -nt

                   read       will      they



Or "they will read".

The moral of this is that your lives used to be fairly simple. An "-e-" before the personal endings always used to indicate a present tense of a second conjugation verb. Now it could mean a future of a third conjugation verb as well. You have to proceed cautiously now, and make sure you have thoroughly mastered your grammar before you start reading. You'll also have to use the dictionary more deliberately and intelligently than you had to before. And that means thinking your forms through before you turn to the dictionary.

IMPERATIVE

Do you remember the formulae you followed for forming the imperative of first and second conjugation verbs? It was this:

           Singular:      stem  +    0

           Plural:        stem  +    te

And so you came up with forms like this: "lauda", "laudate", "mone", "monete", etc. Third conjugation verbs follow the same formulae, but don't forget that pesky short "-e-" stem vowel. If there is something added to it, it changes to an "-i-" (or "-u-" before the ending "-nt"); if there is nothing added to it, it stays short "-e-". So how are you going to form the imperative of the verb "mitto?" Think.

           Singular  mitte  +   0    =    __________



           Plural    mitte  +   te   =    __________

This is how all third conjugation verbs will form their imperatives -- except for four very common verbs. The verbs "duco", and three other verbs you'll get later, form their singular imperatives by dropping the stem vowel altogether: "duc" not "duce". But the plural imperatives are quite regular: "ducite".

VOCABULARY PUZZLES


scribo, -ere         One way to memorize the conjugation of verbs

                     is to learn them with the proper

                     accentuation.  A second conjugation verb is

                     accented on the stem vowel in the infinitive,

                     so say "MOH neh o, moh HEH reh" for the

                     second conjugation verb "moneo, monere". The

                     stress accent on a third conjugation falls on

                     the syllable before the stem vowel.  So say,

                     "SREE boh, SCREE beh reh" for the third

                     conjugation verb "scribo, scribere".

                     Similarly "DOO keh re" for "ducere", "MIT teh

                     re" for "mittere" and so on.



copia, -ae (f)       Another one of those words which have a

                     different meaning in the plural.  In the

                     singular "copia" means "abundance"; in the

                     plural -- copiae, -arum (f) -- it means

                     "supplies, troops, forces".



ad + acc             Means "to" and "toward", always with a sense

                     of "movement to.  Students often "ad + acc".

                     with the dative case of indirect object,

                     which we often translate into English with

                     the preposition "to".  Contrast these two

                     examples: "I am giving you a dollar ("you"

                     would be dative case) and "I am running to

                     you" ("you" would be in the accusative case

                     governed by "ad").



ex, e + abl.         Students sometimes get hung up on when to use

                     "ex" or "e".  Use "ex" before any word you

                     like, but use "e" only before words which

                     start with a consonant.  If you wish, use

                     "ex" only.  That way, you'll always be right.



ago, agere           An idiom with this verb which Wheelock is

                     going use a lot is "ago vitam", which means

                     "to live" (to lead a life).  Another is "ago

                     gratias" + dative, which means "to thank".

                     The person being thanked is in the dative

                     case: "Populus hominibus gratias agent".



duco, ducere         Means "to lead", but can also mean "to

                     think".  This extension is logical: we want

                     our leaders to be thinkers too, don't we?
