The Spanish word 'bocha', meaning 'wooden ball' or referring to a bowling game, traces its origins to the Vulgar Latin word 'bottia', which meant 'bud' or 'knob'. The word evolved through Italian, where 'boccia' meant 'flower bud'. The semantic evolution from a plant bud to a wooden ball is quite intuitive, as both objects share a similar rounded, knob-like shape. The meaning further specialized in Spanish to specifically refer to wooden balls used in bowling-type games.

A related Spanish word is 'boche', which also refers to a ball game, showing how this word family maintained its connection to spherical objects and games in Spanish.

While English doesn't have many direct cognates from this Latin root, the Italian word 'bocce' (from the same origin as Spanish 'bocha') has been borrowed into English to refer to the Italian lawn bowling game. If you're familiar with the game of bocce ball, you'll easily remember that 'bocha' relates to a similar ball-based game.
