The second two determine a verbs's ''t-stem'' and ''s-stem''. These stem alterations are used for further conjugation, the t-stem forming the ''active'' and ''middle perfective participles'', the ''causative voice'', and the ''potential mood'', and the s-stem forming the ''optative''. The t- and s-forms often are identical, however meaning is useally further differentiated by thematic vowels, so completely identical forms are rare. | The second two determine a verbs's ''t-stem'' and ''s-stem''.

The final form determines how a verb with form the perfective aspect. Generally, there are three main strategies for this: the application of suffix '''''-u-''''' directly after the stem (e.g. ''oeliç'' → '''''oeluī'''''), the appication of the suffix '''''-v-''''' after a theme vowel (e.g. ''aedaç'' → '''''aedāvī'''''), or no suffix, with lengthening of the root vowel (e.g. ''legiç'' → '''''lēgī'''''). It should be noted that the perfective is always followed by weak endings. | The final form determines how a verb with form the perfective aspect.

Occassionally, a thematic vowel, weak or strong, may be inserted before the t- or s-stem. This is most common in verbs with a base thematic ''-ā-'', which often functions as a part of the stem (e.g. ''aedaç'' → '''''aedātus | Occassionally, a thematic vowel, weak or strong, may be inserted before the t- or s-stem. This is most common in verbs with a base thematic ''-ā-'', which often functions as a part of the stem (e.g. ''aedaç'' → '''''aedātus''''' ("that loved") '''''aedārit''''' ("they want to love me") vs. ''mavaç'' ("I wander") → '''''mautus''''' ("that wandered") '''''maurit''''' ("I want to wander)). This may occur with other theme classes, although it should be noted that ''-ē-'' is never used, and is always replaced with ''-ī-''. | ||
