The Spanish verb 'chequear' is a relatively modern borrowing from the English word 'check' (meaning 'to verify'), combined with the Spanish verbal suffix '-ear'. This suffix '-ear' is commonly used in Spanish to form verbs, especially when adapting borrowed words from other languages. The result is a verb that means 'to check' or 'to verify' in Spanish, maintaining essentially the same meaning as its English source.

Since 'chequear' is directly borrowed from English, there aren't many simpler etymologically related Spanish words. However, you might encounter variations like 'cheque' (meaning 'check' or 'bank check') and 'chequera' (meaning 'checkbook'), which come from the same English root.

The English word 'check' is obviously related to 'chequear', as it's the direct source word. English speakers can easily remember 'chequear' by noting how similar it sounds to 'check' - it's essentially just 'check' with a Spanish verb ending. Other related English words include 'checklist', 'checkout', and 'checkup', all of which share similar verification-related meanings.
