loquacious

the word 'loquacious' is a direct borrowing from latin 'loquax, loquac-', which itself is derived from the verb 'loqui' (to speak). the suffix '-ax' denotes a strong tendency or disposition, thus 'loquax' literally meant 'inclined to talk'. this latin root 'loqui' is also the source of other english words like 'eloquent' and 'soliloquy', all revolving around the act of speaking. the word entered english in the 17th century, retaining its core meaning of being excessively talkative, a characteristic described by the combined sense of its parts: 'full of talk'.

Structure: loqu (talk) + acious (full of, characterized by) loqu (from latin 'loqui', meaning 'to talk, speak'); acious (from latin suffix '-ax, -acis', forming adjectives meaning 'inclined to, full of').
