To do what you are asked or required to do by a rule, law, or person in authority.
“The company had to comply with strict environmental regulations before the government approved the construction project.”
“If you do not comply with the terms of your lease, you may be evicted.”
In CELPIP Writing (e.g., email to a manager or response to a complaint), use 'comply' to show that you or someone else is following a rule or request. For example, in a formal email, you can write 'I will comply with the new safety regulations.' In Speaking Part 3 (scenario), if you are asked to persuade someone, you can say 'It is important to comply with the building's fire code to ensure everyone's safety.' This demonstrates formal, professional vocabulary.
Synonyms: obey, follow, conform
