The Spanish word 'requinto' refers to a small guitar that is tuned a fifth higher than a standard guitar. It comes from combining the prefix 're-' (meaning 'again') with 'quinto' (meaning 'fifth'). The word 'quinto' itself derives from Latin 'quintus', also meaning 'fifth'. The 're-' prefix combined with the concept of 'fifth' creates a word that literally suggests 'fifth again' or 'raised by a fifth', perfectly describing this instrument's tuning relative to a standard guitar.

Several common Spanish words share this etymology through the Latin 'quintus'. The most straightforward is 'quinto' meaning 'fifth', which you'll encounter in ordinal numbers. You might also see 'quinta' meaning 'country house' or 'farm' (historically referring to a tax of one-fifth), and 'quintal' (a unit of weight).

English speakers can connect this word to several familiar terms that come from the same Latin root 'quintus'. These include 'quintessential' (literally meaning 'fifth essence'), 'quintet' (a group of five), and 'quintuple' (fivefold). The musical term 'quint' also refers to an interval of a fifth, directly relating to the tuning of the requinto guitar.
