The Spanish word 'carné' (meaning 'ID card') comes from French 'carnet' meaning 'notebook' or 'card'. The French term has an interesting origin, tracing back to Latin 'quaterni' meaning 'four each', which itself derives from the Latin word 'quatuor' meaning 'four'. This etymology likely relates to early notebooks or documents being made from sheets of paper folded into four, creating multiple pages. Over time, the meaning evolved from referring to a folded document to more generally meaning an identification card or document in Spanish.

While 'carné' is a relatively common Spanish word itself, there aren't many simpler or more common Spanish words that share its specific etymology. However, Spanish speakers might encounter related forms like 'carnet', which is used in some Spanish-speaking regions as an alternative spelling for the same concept of an ID card.

While English doesn't have any common words directly related to 'carné' through the French 'carnet' path, it does share some distant cousins through the Latin root 'quatuor' (four). English words like 'quarter', 'quartet', and 'quadrant' all derive from this same Latin root, though they've maintained their connection to the concept of 'four' more clearly than 'carné' has.
