IPA: /prɪˈʃrʌŋk/
KK: /priˈʃrʌŋk/
Referring to fabric or clothing that has been intentionally shrunk during production to prevent further shrinking when washed.
I bought a preshrunk t-shirt, so I don't have to worry about it getting smaller after washing.
Preshrunk → It is formed from "pre-" (meaning before) and "shrink" (from Old English "screincan", meaning to contract or become smaller). The word "preshrunk" means that something has been made smaller before it is used, particularly in the context of fabric that has been treated to prevent further shrinking after washing.
Think of something that has been made smaller 'before' ('pre-') it is used — that's why preshrunk refers to fabric that won't shrink again.
