'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.
