Grammatical correctness of 〜好きくない


I saw 未来のミライ the other day. The boy said 〜好きくない regarding many people. Was he
making a grammar mistake?




好きくない is indeed not proper grammar. It is sometimes used by children (and
hence in fiction for children or childlike characters), reanalyzing 好き which
should be a _na_ -adjective 好き（な） as an _i_ -adjective *好きい, hence *好きくない or
*好きかった.
