3. DEFINITION SECTION

3.1. What Does “Unwind” Mean?

“Unwind” (pronunciation: /ʌnˈwaɪnd/) is a versatile verb with both literal and figurative meanings.

  • Literal Meaning: To undo or loosen something that has been wound or twisted, such as thread, tape, or a coil.
  • Figurative Meaning: To relax after stress or tension; to become less worried or anxious.

Dictionary Entries:

  • Cambridge: “To unfasten something that has been wrapped around itself or something else.”
  • Oxford: “To relax after a period of work or tension.”

Etymology: Originates from the prefix un- (meaning “reversal”) + wind (meaning “to twist or coil”). The verb has Old English and Germanic roots, showing a long history in the language.

Examples:

  • Literal: She unwinds the thread carefully to avoid knots.
  • Figurative: He likes to unwind after work by reading a book.

3.2. Grammatical Classification

“Unwind” is primarily a main verb, which can function both:

  • Transitively: Requires an object (e.g., She unwinds the cable.)
  • Intransitively: Does not require an object (e.g., He likes to unwind after work.)

It is classified as an irregular verb because its past forms do not follow the typical -ed ending pattern. Instead, it changes its internal vowel from i to ou:

  • Present simple/base form: unwind
  • Past simple: unwound
  • Past participle: unwound

It belongs to the group of irregular verbs that change their internal vowel (also called strong verbs).

“Unwind” functions as an action verb, describing either a physical action or a mental/emotional state. It can be used in:
