However, depending on the context, you could consider these options:
* "serge" (a type of twilled fabric)
* "urge" (a strong desire or impulse)
These words are not exact homophones, but they are close enough in pronunciation that they could be confused in some cases.
If you are looking for a word that sounds very similar to "surge" but has a different meaning, you could also consider:
* "search" (to look for something)
* "church" (a building for Christian worship)
Ultimately, the best word to use will depend on the specific context and meaning you are trying to convey.
