Usage: Immigration refers to the process of moving into and settling in a new country where you were not originally born. Use this term when discussing people arriving from abroad, rather than for the laws governing them or the place they enter.
Immigration comes from combining the word immigrate with the suffix -ion to form a noun. This construction follows standard English patterns where adding -ion creates words describing an action or process.
