an exclamation of encouragement or approval, typically used to praise a girl or woman for doing something well.
Blend of 'that-a-' (a dialectal form of 'that') and 'girl,' emerging in early 20th-century American English as informal encouragement, parallel to 'attaboy.'
This word shows how casual speech becomes official language—it started as cheerleading slang and made it into dictionaries, revealing how spoken culture shapes what we consider 'real' words.
Mid-20th century colloquial formation ('atta' + 'girl') that presumes female subjects need encouragement differently than men, reflecting gendered reward patterns where 'attaboy' indexed boldness while 'attagirl' often indexed obedience or appearance.
Use 'nice work,' 'well done,' or 'impressive' for direct, non-gendered recognition that applies equally.
