A pal is a good friend. When you're feeling nervous, sad, or lonely after moving to a new town, it can make you feel better to talk to a pal.
If you have a friend you think of as a buddy or a mate, that's a pal. Your earliest pals are often the kids in your neighborhood or at school. As you get older, you have the chance to meet more pals — and when you're friendly with these pals and hang out with them, you can say you "pal around" with them. Pal is originally a Romany word meaning "brother," from the Sanskrit bhrata, also "brother."
