Which is the closest antonym for word typically?

The closest antonym for "typically" depends on the context, but some strong contenders are:

* Atypically: This directly negates the usual or common occurrence implied by "typically."

* Unusually: This emphasizes the rarity of the event or characteristic.

* Exceptionally: This highlights the deviation from the norm, suggesting something extraordinary.

* Rarely: This emphasizes the infrequency of the occurrence.

* Uncommonly: Similar to "rarely," this suggests the event or characteristic is not common.

The best antonym will depend on the specific situation and what you want to emphasize.

If you are discussing a trait that is generally uncommon, "unusually" or "exceptionally" might be more appropriate.
