Commit to paper at the end of 14 across
I believe the answer is:
record
'commit' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe you can see a link between them that I can't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for record that I've seen before include "put down to the occasion" , "Note - disc" , "Preserve in writing or electronically" , "a hole in one?" , "Make a single" .)
