Attagirl is a short, warm shout of well done aimed at a girl, a woman, or a female animal — the sister of attaboy. It is what you call to a child who has just tied her shoes, or to a dog that has finally sat when asked. It comes from saying That's the girl! so fast that the words melt. You will hear it from coaches, parents, and people talking to pets; it is friendly and spoken, not a word for essays. As a noun it is rarer: you can give someone an attagirl, meaning that little burst of praise. Though actually, to an adult woman at work it can sound old-fashioned or a bit pat-on-the-head, the way some praise talks down. With children and animals it still feels kind. There is no deep extra sense hiding here — it is encouragement, and the gender in the word is real, not a joke.
