In English, an Auxiliary verb is a verb that changes or helps another verb. Auxiliary means "extra" or "different". Auxiliary verbs like do can be used to make a question. These verbs are usually used with other verbs.

Basic examples[change | change source]

Below are some sentences that use auxiliary verbs from English, Spanish, German, and French, with the auxiliary verb in bold:

a. Do you want tea? do is an auxiliary verb that changes the main verb want to make a question – see do-support.
b. He has given his all. has is an auxiliary used to say the perfect form of give.
c. He cogido tu lápiz. he is an auxiliary accompanying the main verb coger, used here to make a compound verb, the perfect present of the verb coger.[1]

d. Das wurde mehrmals gesagt. wurde 'became' is an auxiliary used to make the passive voice in German.[2]

These auxiliaries help make a question, show tense, or make passive voice. Auxiliaries like these usually appear with a normal verb that carries the main meaning of that part of the sentence.
