What is the opposite of smell?

There isn't a single word that perfectly captures the opposite of "smell". It depends on what aspect of smell you're looking for the opposite of. Here are a few options:

1. Absence of smell: This could be described as odorless, unscented, or scentless.

2. Inability to smell: This is anosmia, the complete lack of the sense of smell.

3. Disliking a smell: The opposite of enjoying a smell could be disgusting, repulsive, or offensive.

4. The opposite of the physical act of smelling: This could be tasting, hearing, seeing, or touching, as these are other senses.

Ultimately, the best word to use depends on the specific context.
