You need to define your words that you selected and then use a thesaurus.
Find all the similar words that mean something like the words you have selected.
The reason we do this is because our brains work like internet browsers. Our brains search for pictures that associate with each word we find. This forces us to be instantly creative because each word acts as a different visual clue to a final solution.
The job is to take the best ideas to finalize a concept.
