What figure of speech is gingerly?

"Gingerly" is not a figure of speech itself. It's an adverb, meaning "with great care or caution."

However, "gingerly" can be used to create other figures of speech. For example:

* Metaphor: "He walked gingerly across the minefield of broken glass." (Implies a dangerous situation)

* Simile: "She handled the fragile vase as gingerly as a mother holding her newborn." (Compares the action to something delicate)

So, while "gingerly" isn't a figure of speech on its own, it can be used to create figurative language.
