feeble-minded child; slow learner; poor student
Dated and potentially offensive term for a child with intellectual disability or very low academic performance. Modern usage is rare and often replaced by more respectful language.
In old educational settings, the term '低能児' was sometimes used.
He was treated as a slow learner at school, but actually he just had a learning disability.
Modern, neutral term for intellectual disability, unlike the dated and derogatory 低能児.
Refers to specific learning disabilities, not a general label for low intelligence.
Standard kanji spelling.
Irregular kanji usage; 脳 is not standard here.
Compound of 低能 (low intelligence) and 児 (child). The exact historical origin is uncertain, but it reflects older, now-discouraged terminology for intellectual disability.
