起源と歴史

From 頼む (tanomu, to rely on/to request) with the i-adjective suffix もしい. The suffix conveys 'having the quality of' or 'worthy of' the base verb, so 頼もしい literally means 'worthy of being relied upon.' Attested from classical Japanese literature, where it described trustworthy patrons or allies.
