Desfallecer conjugation
Table of Contents
Desfallecer is a Spanish verb which translates into English as “to faint, weaken”.
Below are all of the conjugations for desfallecer in Spanish, in all three moods (indicative/indicativo, subjunctive/subjunctivo and imperative/imperativo) and all of the tenses, for each pronoun.
The vosotros pronoun is mainly used in mainland Spain, and is the informal second-person plural – it could be considered the Spanish version of “y’all”. It is rarely found in Latin America, where ustedes is used instead.
The vos form is used instead of tú in some Spanish speaking countries of South America, especially the Southern Cone (e.g. Argentina and Uruguay) and has a different conjugation.

The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he desfallecido and hubiera desfallecido. These are the equivalent of English’s ‘have’ (e.g. have fainted).
