レギュラー
レギュラー · regyuraa · JLPT N1 · na-adj
regular
レギュラー is the katakana of 'regular': sounds like 'regular' with the r-sounds softened into Japanese vowels.
Katakana borrows English words by sound: レ-ギュ-ラ-ー spells out 'Re-gyu-ra-a', close to 'regular'. A regular player on a team is a starter, and the word means the same in both languages.
