Ablaut in Present Stems

Present stem is formed from a verb stem with either a zero- or lengthened-grade ablaut:

  • zero-grade: causative, derivative, formative (b) verbs;
  • lengthened-grade: basic verbs, a-verbs, u-verbs, and formative (a) verbs.

Exception

Long verbs make their present tense stem with short-grade ablaut, see below.

Reminder

Derivative and causative conjugations have only zero-grade stem (→@@).

Long conjugations have no lengthened-grade stem.

Thematic and Athematic Presents

Forms built on the present stem follow either a thematic or an athematic conjugation.

  • thematic conjugation: derivative and causative verbs.
  • athematic conjugation: all other verbs.

Late Tarquesta

Thematic conjugation eventually spread into the rest of secondary verbs, except u-verbs: fára > fárea, talata > taltea, síria > sírea, istya > istea.

Tense Endings

Tense endings are added after a theme vowel in thematic conjugations, or directly to stem in athematic conjugations.

  • present tense endings: -ya in derivative, causative verbs, and formative verbs; -a in other verbs;
  • imperfect tense ending: -ane in all conjugations;

Particular Formations

Verbs Defective in Present

Verbs ending in -e(ng)a are defective and use their aorist tense form for present: te(ng)a- > tea shows, is showing.
