There are two conjugations and 11 irregular verbs. Tenses or moods are formed by inflecting the stem, and in the past and habitual past tenses and the conditional mood also by leniting any initial consonant. The inflected tense and mood forms are: present indicative, present habitual indicative (differs from present only in the verb "bí" "to be"), future, past indicative, past habitual indicative, conditional, imperative, present subjunctive, and past subjunctive. Verbs also have a verbal noun and past participle, and progressive constructions similar to those using the English present participle may be formed from the verbal noun and an appropriate tense of "bí".
