IPA: /ʌnˈwaɪndər/
KK: /ʌnˈwaɪndər/
A tool or device that is used to unwind something, such as a coil or a roll of material.
The unwinder helped to easily release the tape from the roll without tangling.
Unwinder → It is formed from "un-" (meaning not or opposite of) and "winder" (from the verb "wind", meaning to twist or coil). The word "unwinder" refers to something that reverses the action of winding, or untwists something that has been coiled.
Think of 'un-' meaning not or the opposite, and 'winder' as something that twists or coils. So, an unwinder is something that undoes the twisting action.
