Auxiliar + infinitivo/gerundio/participio para expresar aspecto y modalidad
A verbal periphrasis is a structure formed by a conjugated auxiliary verb + a non‑finite verb form (infinitive, gerund, or participle) that works together as a single meaning unit. Periphrases let you express aspect/modality such as start, repetition, intention, duration, result, and more.
There are three main types according to the non‑finite form: infinitive, gerund, and participle periphrases.
Infinitive periphrases often express beginning, end, repetition, intention, or a mild obligation.
Gerund periphrases express ongoing process, insistence, gradual change, duration, continuity, or a resulting state.
Participle periphrases indicate the state or result of an action. Important: The participle must agree in gender and number with the noun it modifies.
Periphrases add natural, nuanced expression to your Spanish. A tutor can help you internalize the patterns and choose the right construction in context.
