Tapping out a message (6)
I believe the answer is:
typing
This clue might be a double definition.
'tapping out' is the first definition.
Although both the answer and definition are present participle verbs, I can't see how one could define the other.
'a message' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for typing that I've seen before include "Using one form of keyboard" , "Keyboarding" .)
