If it's 4a, I didn't parse it like that, rogissimo. I had the definition as "for instance", and "put on" giving 3 letters, then 3 letters from the next two words.
4d was one of the last ones in. I could see the anagrist but didn't know the word. Fortunately the final 7 letters were guessable with the help of crossers. I still had to look up the word after entering it in the grid.
