The word "donned" is a verb that means to put on or get dressed in clothing or accessories. It is often used when someone is putting on an item of clothing (such as a coat, hat, or uniform) as part of their preparation for an activity or event.
The word "donned" comes from the verb "don," which has its origins in the Middle English word "donne," meaning "to put on." This term is derived from the Anglo-French term "doner," meaning "to give." Thus, "don" implies the act of putting something on oneself, as if you are giving yourself clothing.
