A newcomer is someone who has recently moved into an area or joined a group. They might be a little unfamiliar with how things work.
When people talk about newcomers, they usually mean people who are new to a place, like a neighborhood or a city. For example, if you just moved to a new town and your coworkers ask, "How do you like it here?" you're likely being considered a newcomer. This word can also be used for people joining any kind of group, whether that's a social club, a sports team, or even an online community. When someone says, "We have some newcomers on the team," they're talking about people who are new to the group and might need a little help getting settled in.
One who has recently come to a community; a recent arrival.
