Heavy Construction

The Allen and Greenough is still under construction; so some links may not work quite the way you would expect.


The Present Stem is formed from the Root in all regular verbs in one of the following ways: -

a. In the First, Second, and Fourth conjugations, by adding a long vowel (á-, é-, í-) to the root, whose vowel is sometimes changed: as, vocá-re (VOC), moné-re (MEN, cf. meminí), sopí-re (SOP).[1][Most verbs of the First, Second, and Fourth Conjugations form the present stem by adding the suffix -yeo to a noun-stem. The á of the First Conjugation is the stem-ending of the noun (as, plantá-re, from plantá-, stem of planta). The é of the Second and the í of the Fourth Conjugation are due to contraction of the short vowel of the noun-stem with the ending -yeo-. Thus albére is from albeo-, stem of albus; fíníre is from fíni-, stem of fínis. Some verbs of these classes, however, come from roots ending in a vowel.]

NOTE: Verb-stems of these conjugations are almost all really formed from noun-stems on the pattern of older formations (see § 174).

b. In the Third Conjugation, by adding a short vowel eo[2][This is the so-called ``thematic vowel.''] to the root. In Latin this eo usually appears as iu, but e, is preserved in some forms. Thus, tegi-s (root TEG), ali-tis (AL), regu-nt (REG); but tege-ris (tege-re), ale-ris.
