Etymology: Derived from the Japanese words 'funa' (船) meaning 'boat' in some contexts but more likely 'funa' as an older or dialectical form related to 'field' (possibly linked to 'hara' or 'no') and 'ki' (木) meaning 'tree'. However, most commonly interpreted as originating from 'funa' (船) + 'ki' (木), possibly indicating a boat-shaped tree or more plausibly a topographic name for someone living near a tree by a boat landing or riverside. Alternatively, written with kanji like 船木, it literally means 'boat tree' or 'tree associated with a boat'.
