verb · CEFR A1

Stands for 'does not'. You use it to say that a person, animal, or thing is not doing something or that something is not true.

For teachers: Abbreviation for 'does not'. The negative contraction of the third-person singular present indicative of 'do', used as an auxiliary to form negative statements and questions.
