Many players mistakenly believe that homonyms like 'knight' and 'night' are always valid clues, but the official rules treat them differently.
No, according to the Czech Games Edition Official Rulebook, soundalike clues are only allowed if they refer to the meanings of words.

Official Rule Breakdown
Regarding the use of homonyms in Codenames, the official rules state that same-sounding words with different meanings and spellings are considered different words. For example, 'knight' is not a valid clue for 'NIGHT' because they do not share a meaning. However, words that are spelled the same are treated as the same word regardless of pronunciation; for instance, 'bow' (as in archery) and 'bow' (as in a ship) can be used as a single clue for both …
Example Play Situation
Alice is the Spymaster. She wants to hint at 'SHIP' and 'THEATER'. She says 'bow: 2'. Bob, her field operative, correctly identifies that 'bow' is spelled the same for both meanings and guesses the two cards.

House Rules
[HOUSE RULE] Some groups choose to play more liberally by allowing all soundalikes (e.g., using 'night' for 'KNIGHT') to increase the fun factor.
Common Misconceptions
- Thinking all homonyms are automatically valid clues
- Assuming the Codenames app rules apply to the physical board game
- Confusing spelling-based identity with sound-based identity
