However, depending on the context, these words might be considered close:
* Attacked: This word sounds the same but has a very different meaning.
* Atached: This is a misspelling of "attached," but it could be a homonym if someone accidentally misspells it.
If you're looking for a word that means "attached" in the sense of being emotionally connected, "devoted" might be a good option.
Ultimately, the best alternative will depend on the specific situation and the intended meaning.
