The unclued entries (two hyphened) are all synonyms. Each of five clues contains a word that must be removed to enable the clue to be solved. These words can all be augmented by a letter (the five letters appear in sequence in the completed grid, and must be highlighted) to form five more words, which, treated singly or combined in pairs, form nine items. One is a synonym of one of the unclued entries.
