The Spanish word 'migajas' (meaning 'small crumbs') comes from the Latin word 'mica', which meant 'crumb' or 'small particle'. The Latin word evolved into the Spanish word 'miga' (meaning 'crumb'), and then the diminutive suffix '-aja' was added to form 'migaja' (meaning 'small crumb'). Finally, the plural suffix '-s' was added to create 'migajas', referring to multiple small crumbs.

A simpler and more common related Spanish word is 'miga', which means 'crumb' or 'breadcrumb'. While 'miga' refers to a regular-sized crumb, 'migajas' specifically refers to tiny crumbs due to the diminutive suffix '-aja'. You might hear 'miga' in phrases like 'miga de pan' (bread crumb) or 'migas' (a Spanish dish made with breadcrumbs).

While there aren't many common English words directly related to 'migajas', the word 'mica' (the mineral) comes from the same Latin root 'mica'. This connection makes sense because both breadcrumbs and the mineral mica can be found in small, flaky particles. The mineral mica got its name from Latin because it typically breaks into small, thin sheets or particles, similar to how bread breaks into crumbs.
