Auxiliary verb
Which helper verb builds the question, the negative or the tense?
Significado
A helper verb works with another verb to build a question or negative, show time, or add a meaning such as ability. The other verb names the main action or state, while the helper carries part of the grammatical message. Some languages use several helper verbs, while others express these meanings mostly through endings or have no such helpers. Endings change the word itself; an auxiliary verb adds a helper alongside the main verb.
Como identificar
Look for a verb used alongside another verb that builds its question, negative, time form, or added meaning rather than naming a separate action.
Na tua língua materna
An auxiliary verb is a helping verb that works with another verb to express time or how an event unfolds. Estar with a form ending in -ndo presents an action in progress, while ir with an infinitive, a form such as sair, often presents a future action. Present-tense ter with a past participle, a form such as estudado, usually describes repeated or continuing activity up to now.
A Luiza está preparando o almoço.
Está combines with preparando to show an action in progress.
A gente vai sair depois do almoço.
Vai combines with the infinitive sair to present a future action.
Eu tenho acordado cedo esta semana.
Tenho acordado describes repeated waking up over the recent period, not just one completed occasion.
Na tua língua de aprendizagem
An auxiliary verb is a helper used with a main verb, the verb naming the action or state. English uses be, have, and do to build verb forms, questions, and negatives, and helpers such as can and will to express meanings like ability and future time. When do, does, or did is used, the main verb stays in its base form, the form listed in a dictionary, such as work.
Do you need help?
Do builds the question; need names the main action.
She doesn't work on Fridays.
Doesn't is does not; work stays in its base form without -s.
Mia is cleaning the kitchen. She has cleaned the bathroom.
Is builds a form for an action in progress; has builds a form for a completed action connected to now.
Learners whose language forms questions and negatives without helper verbs may omit do or use it where another helper is already present. Learners whose language marks person or tense on the main verb may add an ending after does or did instead of using the base form.
