What does the verb 'settled' mean?
The verb settled can have a few meanings. Settled originally meant when moving to a new land or residence, you would have things set up to live there---not necessarily all you needed or wanted, but you were there at least for the time being. People who immigated to new colonies were Settlers who settled a specific location. Settled can also mean calm or unmoving, with a pleasant or satisfied feeling of being "at home". It means to stop moving or a person or an object or element to be comfortable with its surroundings. Example: I settled into my new house wiith a sense of adventure. In areas where parties have an issue with each other that needs resolved, the issue can be called "settled" when the issue is resolved. Example: The insurance company settled with the insured. Or... The civil case was settled out of court. Even between neighbors or friends, "They settled their differences." In modern slang it can also mean that you took whatever came along your way. For instance, "The woman was bored with her life, so she settled for the first job offer that came her way." Settle and settled, present and past tenses, have similar meanings. In chemistry, one part of a mixture can "settle" and separate out from the mixture.
