Meaning

To serve dual functions; to double as something else; in negative constructions, to be unable to do something out of hesitation or propriety.

A Group 2 (ichidan) verb with two distinct uses: (1) to hold multiple roles simultaneously, as in 部長を兼ねる (to also serve as department head); (2) in the negative pattern ～かねる, to be reluctant or unable to do something because it would be improper or difficult, as in 同意しかねる (unable to agree). The second use is especially common in polite refusals in formal Japanese.
