用法筆記
Almost always in negative constructions. The fixed phrase 'not half bad' is a British informal idiom meaning 'surprisingly good.' In British slang, 'not half' alone can mean 'very much' ('Do you like it? — Not half!'). Outside these expressions, 'not half' before an adjective simply negates the degree ('not half as tall' = much less tall).
