Spell out English book on energy at speed (9)
I believe the answer is:
enumerate
'spell out' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'english book on energy at speed' is the wordplay.
I cannot really understand how this works, but
'english' could be 'e' (abbreviation) and 'e' is found in the answer.
'on' could be 'at' (I've seen this in other clues) and 'at' is present in the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for enumerate that I've seen before include "Count - list" , "Specify individually" , "List one by one" , "Count or mention items one by one" .)
