The Spanish word 'holgado' (meaning 'loose, spacious' or 'at ease') comes from the verb 'holgar' ('to rest, be idle') combined with the past participle suffix '-ado'. The verb 'holgar' traces back to the Latin word 'follicare' meaning 'to pant or breathe heavily', which itself derives from 'follis' meaning 'bellows' (a device for blowing air). The semantic evolution from a bellows to the modern meaning is quite interesting - just as bellows need space to expand and contract while blowing air, something that is 'holgado' has comfortable space or room. Similarly, the connection between breathing heavily and resting ('holgar') likely comes from the association with catching one's breath or breathing easily after exertion.

A simpler and more common related Spanish word is the verb 'holgar' meaning 'to rest' or 'to be idle'. You might also encounter 'huelga' meaning 'strike' (as in a worker's strike), which comes from the same root - the connection being that striking workers are deliberately not working or being 'idle'.

While there aren't many common English words directly related to 'holgado', the Latin root 'follis' (meaning bellows) did give us some specialized English terms. For example, 'follicle' (as in hair follicle) comes from this same Latin root, as it originally referred to a small air-filled sac, similar to a tiny bellows.
