February 2017 Monthly Crossword
Medium

This month's puzzle marks 16, 1, 3 - the first of its kind. Five clues consist of wordplay only (i.e. are undefined). These lead to role fulfillers, where the grid entry should be the actual role fulfilled in each case. Two further normal clues lead to the medium, both generically (in full) and specifically (only partially). The remaining twenty clues each contain a superfluous word, but are otherwise normal. The initial letters of the extra words spell, in order, the item of which 16, 1, 3 was the first (2 words), one of the missing elements from the medium (1 word) and an acronym related to the role fulfillers.
