Homonym: Ex- (Former)
The prefix "Ex-" is derived from Latin, meaning "out of" or "from." It is commonly used in the English language to indicate something that was once in a particular state or relationship but is no longer so. For example, an ex-husband refers to a former spouse, while an ex-employee denotes someone who previously worked for a company.
In addition to personal relationships, "Ex-" can also apply to objects or concepts. An ex-president is someone who has completed their term in office, and an ex-partner signifies a previous business associate. This prefix helps clarify the past status of individuals or items.
