Sweater creates thirst (1-5)
I believe the answer is:
t-shirt
'sweater' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'creates thirst' is the wordplay.
'creates' indicates an anagram.
'thirst' is an anagram of 'T-SHIRT'.
Can you help me to learn more?
(Other definitions for t-shirt that I've seen before include "Casual vest-like garment much worn by youth" , "Simple garment" , "Collarless pullover shirt" , "Light garment for upper body, often with pictures or slogan" , "Short-sleeved cotton top with no collar" .)
