The term 'SPUD' can be defined by three different crossword solutions: TATER (5 letters), POTATO (6 letters), and SPADE (5 letters). TATER is a slang term for POTATO, which is a starchy tuberous crop from the perennial nightshade Solanum tuberosum. SPADE is a tool used for digging, typically with a flat rectangular blade and a long handle. Therefore, the term 'SPUD' can be interpreted as a combination of the two words, referring to a POTATO that has been dug up with a SPADE.
