Pro Tip
Distinguish 'clue' from 'clue' vs. 'clew'
While 'clue' and 'clew' are pronounced the same, 'clue' refers to information or a hint, while 'clew' (archaic) means a ball of thread. In modern usage, 'clew' is rarely used except in the phrase 'clew line' (nautical term).
Gold Rule
Use 'clue' for solvable mysteries
Reserve 'clue' for contexts where information helps solve a problem, mystery, or puzzle. Do not use it for general advice or unrelated facts.
Plural form
The plural of 'clue' is 'clues'. Example: 'The detective gathered all the clues.'
Word Origin
From Middle English 'clue' (a ball of thread), derived from Old French 'clue' or 'clou' (a ball of thread), from Latin 'clavis' (key). The sense of 'a guiding piece of information' emerged in the 17th century, likely from the idea of a thread guiding through a maze (like Theseus in Greek mythology).
Usage Notes
Commonly used in detective fiction, crime investigations, and everyday problem-solving. The plural form is 'clues'. Avoid confusing with 'clew' (a ball of thread), though historically they were the same word.
