'Verbs' presents data concerning conjugation class, regularity, irregularity, frequency, and a person number hierarchy before examining regular verb inflection. Transparent past tense verbs provide the template for analysis of all tenses, moods and aspects. The present indicative has a Ø tense-mood-aspect morpheme. Present tense irregular verbs, including suppletives, evince vocalic and consonantal mutability. The key to irregular pluperfect, past and future subjunctive lies in the stems of the irregular preterite—the most marked of all past tense verbs. The final chapter demonstrates verbal derivation using theme vowels, intermediate suffixes, and prefixes. All 4 chapters provide grammars of the phenomena examined. A Postscript presents verbal hierarchies in the FrePOP lexicon.
