Struck by a Start the Week podcast on writing and epic stories, the comment that left me most satisfied was the phrase during the discussion relating to how writers hoard words, how they keep lists of verbs, and (as I interpret it) how they use these as a treasure store and inspiration to seed the growth of longer collages and stories.
Single words often have powerful connotations, especially the verbs, and it is fascinating to see how they spawn actions of their own in writers and during the process of writing.
