What is the difference between bridge and bridging?

Could you please elaborate on the distinction between 'bridge' and 'bridging' in the context of cryptocurrency and finance? I've often heard these terms used interchangeably, but I'm curious about their specific meanings and how they differ. Is 'bridge' simply a structure or platform that facilitates the transfer of assets between two blockchains, while 'bridging' refers to the actual act of transferring assets across these bridges? Or am I missing something more nuanced in this distinction? Your clarification would be greatly appreciated.
