The Spanish word 'cheto' is a modern slang term that comes directly from the English word 'cheater'. This is an example of how English words sometimes get adapted into Spanish with modified spelling to match Spanish pronunciation patterns. The 'ea' in 'cheater' becomes 'e', and the final '-er' becomes '-o', making it fit better into Spanish morphology.

Since 'cheto' is a direct borrowing from English, there aren't any simpler or more common Spanish words that share its etymology.

The English word 'cheater' is obviously related, being the direct source of 'cheto'. English speakers can easily remember this word by thinking of 'cheater' and just adapting it to Spanish pronunciation. Other related English words include 'cheat', 'cheating', and 'cheats' - all carrying the same basic meaning of someone who breaks rules or acts dishonestly.
