This is false, and the opposite is true!
A want, used as a noun, refers to something that is not necessary, but something that is wanted, desired only.
A need, in contrast, refers to something that is necessary, so it is not merely something that is wanted, but something that is very essential.
While both have to very different meanings, both have a definition of meaning something small (alley - small passage, pony - small horse, pour, or amount of money). Both are 6 letters, but when made plural, are spelling differently (alleys - just add s, ponies - drop the y, add ies). Both are Latin in origin, changing letter to French. But alley is late middle English, with pony being from the mid 17th century.
