To correspond in every detail (7)

I believe the answer is:

totally

I'm a little stuck... Click here to teach me more about this clue!

'to correspond in every detail' is the definition.
I can't tell whether this definition defines the answer.

'to correspond' is the wordplay.
'correspond' becomes 'tally' (synonyms).
'to'+'tally'='TOTALLY'

Can you help me to learn more?

(Other definitions for totally that I've seen before include "in every respect" , "Dead" , "Allowing no exception" , "to the nth degree" , "Absolutely" .)

I've seen this clue in The Irish News.
