assiduously の語源・成り立ち Etymology
assiduously は assiduous＋-ly。assiduous はラテン語 assiduus「絶えずそばに座る、勤勉な」にさかのぼり、ad-「〜へ」＋sedere「座る」に分かれます。『席を離れず取り組む』感覚から「熱心に」となり、関連語に assiduous、session があります。
Assiduously comes from assiduous plus -ly. Assiduous goes back to Latin assiduus, from ad- and sedere, meaning "to sit," with the sense of staying seated near a task. From the idea of not leaving one's place, it developed the meaning of working steadily and with care. A related English word from the same root is session.
