Quickly put into words (7)
I believe the answer is:
express
I believe this clue is a double definition.
'quickly' is the first definition.
(I've seen this before)
'put into words' is the second definition.
(I've seen this in another clue)
(Other definitions for express that I've seen before include "High-speed; specific" , "Former journalists < not stopping < newspaper" , "Fleet" , "Verbalise - very fast" , "haste" .)
