Yes, you can say "kid" to a girl. "Kid" is a gender-neutral term used to refer to a child and is interchangeable with the word "child." It's simply a less formal way of referring to someone young.
"Kid," in this context, doesn't have any inherent gender association. It applies equally to boys and girls. Think of it as synonymous with "child" or "young person."
For example:
- "That kid is really good at soccer!" (referring to either a boy or a girl)
- "Are the kids behaving themselves?" (referring to a group of children, regardless of gender)
Therefore, using the term "kid" to refer to a girl is perfectly acceptable and common in everyday language.
