FAQ
Frequently Asked Questions
No, it is extremely rare. The word 'tenfold' is universally preferred in modern English.
Yes, though rarely. It means 'to make ten times as great' (e.g., 'to decuple the amount').
It comes from the Late Latin 'decuplus', from Latin 'decem' (ten) + '-plus' (fold).
'Decuple' is the correct spelling meaning 'tenfold'. 'Decuple' is not a standard English word and is likely a misspelling.
