The phrase "gave someone gate" is an old-fashioned term that means to dismiss someone or make them leave. But, there are many synonyms that can be used in its place. Some common alternatives include "fired," "terminated," "let go," "sacked," "discharged," and "dismissed." These words are often used in a professional setting to denote the ending of a job contract or where an employee is no longer needed. However, other synonyms such as "banished," "ejected," "expelled," "evicted," or "exiled" imply more of a permanent removal from a person or group. Overall, while the phrase "gave someone gate" may be outdated, there are plenty of synonyms available to convey the same meaning.
