Definition: "split"

This is a charade - a technique where you combine separate word parts or words in sequence to build the final answer.

Take the first letter of 'Cameron' and add it to a word meaning 'quit'. The parts combine in the order they appear in the clue.

Answer: CLEAVE | Take C (Cameron's first letter) and add LEAVE (quit) to get C + LEAVE = CLEAVE (split)
