We'll is a contraction of “we will.” It's a shortened way of saying those two words by squishing them together and replacing the missing letters with an apostrophe.

When you say we'll, you're talking about something you and at least one other person plan to do in the future. “We'll meet you at the park after school” means the same thing as “We will meet you at the park after school,” just faster and more natural in conversation.

Contractions like we'll make English sound friendlier and more relaxed. Compare “We will have pizza for dinner” with “We'll have pizza for dinner.” The second version feels more like actual speech. When you write we'll, you're capturing the rhythm of how people really talk.

Be careful not to confuse we'll with well (without the apostrophe), which means something completely different. “We'll do our best” and “We did well” use words that sound identical but mean different things. The apostrophe in we'll is your signal that it's the contraction meaning “we will.”
