*The designation 1+2 refers to the first two parts, which would actually both be needed to determine endings only with the third / third-io conjugations (e.g., reg-unt, cap-iunt).  Otherwise, the second part alone can usually allow you to construct the correct endings for the forms here indicated by the 1+2
