What's the Rule?
In writing, the dialogue tag is the bit of text that tells the reader who spoke what dialogue:
"Are you hungry?" Jimmy asked.
"Please don't suggest we have raw fish," Oscar said.
"You only hated it because the first piece you had wasn't fresh," Jimmy insisted.
"Or because it tasted like gym socks," Oscar complained.
There are dozens if not hundreds of dialogue tags--blurted, groaned, sighed, cried, shouted, yelled, griped, moaned, and the list goes on.
But there is a rule in the writing world that we should pretty much only use "said" and "asked."
