Sustuyamos

Sustuyamos is a term that arises in discussions of Spanish verb forms, but it is not a standard form in modern correct usage. In standard Spanish, the present subjunctive first-person plural of the verb sustituir (to substitute, replace) is sustituyamos. The form sustuyamos differs by the insertion of a different syllable sequence and is not listed as an accepted present subjunctive form in authoritative dictionaries of Spanish.

Origin and linguistic context

The related verb sustituir comes from Latin substituere. In Spanish orthography and pronunciation, verbs in the -uir group typically show a spelling and pronunciation change in the present subjunctive for the nosotros form (for example, concluir → concluamos, construir → construyamos). The grammatically correct present subjunctive for sustituir, therefore, is sustituyamos.

Usage notes

Because sustuyamos is not recognized as a standard form, it should not be used in formal writing. If encountered, it is usually the result of misspelling, hypercorrection, or nonstandard regional usage. In contexts requiring the subjunctive with nosotros, the preferred form is sustituyamos.

Alternative meanings

There is no widely attested meaning of sustuyamos as a separate lexical item in contemporary Spanish. It is not typically treated as a distinct verb form with its own dictionary entry, but rather as a nonstandard variant of sustituir’s present subjunctive.
