Etymology edit

Purportedly from a calque of Japanese (あたま)(かた) (atama ga katai, resistant to new ways of thinking, literally having a hard head). Possibly originally from unattested Taiwanese Japanese *(あたま)コンクリート (atama konkurīto, literally concrete-head), which can be reconstructed from the phonetic borrowing of Taiwanese Mandarin 阿達馬孔固力阿达马孔固力 (ādámǎ kǒnggùlì, “concrete-head”).
