How to count up completely (7)
I believe the answer is:
totally
'completely' is the definition.
(synonyms)
'how to count up' is the wordplay.
I cannot really see how this works, but
'to' is found in the answer.
'count' could be 'tally' (tallying is a kind of counting) and 'tally' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for totally that I've seen before include "without reserve" , "Fully, completely" , "Allowing no exception" , "Wholly" , "Utterly" .)
