Aeranir: Difference between revisions

[[File:Stse.png|right|250px]]The verb in Aeranir is primarily made of three parts: ''stem'', ''theme'', and ''ending'', with an optional forth category, the ''suffix'', for forming the perfective.  The stem carries the semantic content of the word, and can also be conjugated to carry modal imformation.  The theme describes how the stem interacts with the ending, and can also be changed, along with the stem and endings, to express a variety of different grammatical meanings.  Endings indicate the voice, aspect, person, number, and gender of the most oblique argument in the DGA scheme.

The first of these reference forms determines a verb's ''base thematic class'', or what theme vowel is used in its indicative imperfective forms.  There are four main thematic classes; one weak or null class, wherein the ending is applied directly to the stem, and three strong classes, wherein a thematic vowel is inserted between the stem and the ending.

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 ''desiderative''.  The t- and s-forms often are identical, however meaning is useally further differentiated by thematic vowels, so completely identical forms are rare.

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'' ("I work") → '''''oeluī''''' ("I worked")), the appication of the suffix '''''-v-''''' after a theme vowel (e.g. ''aedaç'' ("they love me") → '''''aedāvī''''' ("they loved me")), or no suffix, with lengthening of the root vowel (e.g. ''legiç'' ("I choose") → '''''lēgī''''' ("I chose")).  It should be noted that the perfective is always followed by weak endings.

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-''.
