Necesitar Conjugation | How to Conjugate Necesitar in Spanish

Necesitar means “to need” or “to require.” You will learn its fully regular -AR conjugation and the core patterns necesitar algo, necesitar + infinitive, and necesitar que + subjunctive.

Necesitar conjugation at a glance

Verb type: Regular AR. Necesitar keeps the stable stem necesit- and takes ordinary -AR endings. Its gerund necesitando — “needing” — and participle necesitado — “needed” — are regular.

Necesitar gerund, past participle, and infinitive

The infinitive names the verb, the gerund supports progressive constructions, and the past participle combines with haber — “to have” as an auxiliary — in compound forms. The participle necesitado remains invariant in those compounds.

Infinitive	necesitar	to need
Gerund	necesitando	needing
Past participle	necesitado	needed

Necesitar meaning and essential uses

Necesitar — “to need / require” — is commonly transitive: Necesito ayuda. — “I need help.” RAE also records an intransitive construction with de, but direct-object use is the central modern learner pattern.

Before another action with the same subject, use necesitar + infinitive: Necesito descansar. — “I need to rest.” With a different subject, necesitar que + subjunctive is common: Necesito que vengas. — “I need you to come.”

Necesitar conjugation pattern

The stem necesit- remains unchanged throughout the core paradigm. Forms such as necesito — “I need,” necesité — “I needed,” and necesite — “that I need” — take normal -AR endings.

There is no stem change, spelling alternation, irregular preterite stem, irregular future stem, irregular gerund, or irregular participle.
