Here's why:
* Homophones and homonyms are simply words that sound alike or are spelled alike. They don't inherently create a particular effect or enhance meaning in a text.
* Language techniques are deliberate choices made by writers to achieve a specific effect. They are tools used to convey meaning, evoke emotion, or create a particular tone.
However, homophones and homonyms can be used as part of other language techniques, like puns or wordplay. For example, a writer might use the homophones "to" and "too" in a sentence to create a humorous or ironic effect.
To summarize:
* Homophones and homonyms are not language techniques in themselves.
* They can be used as part of other language techniques.
* Their primary function is to explore the relationship between sound, spelling, and meaning in language.
