The term 'SPADES, FOR ONE' can be solved by the four-letter word 'SUIT'. A SUIT is a set of clothing consisting of a jacket and trousers or skirt, typically made from the same fabric and worn together. Suits are traditionally worn by men, but women's suits have become increasingly popular in recent years. The term 'spades, for one' refers to the fact that spades is one of the four suits in a deck of playing cards.
