Very precise girl with UCAS forms (8)
I believe the answer is:
surgical
'very precise' is the definition.
'surgical' can be an answer for 'precise' (I've seen this before). I am unsure of the 'very' bit.
'girl with ucas forms' is the wordplay.
'with' means one lot of letters go next to another.
'forms' is an anagram indicator.
'girl' put after 'ucas' is 'ucasgirl'.
'ucasgirl' anagrammed gives 'SURGICAL'.
Can you help me to learn more?
(Other definitions for surgical that I've seen before include "For use in the theatre" , "(Of action) precise, incisive" , "Ugli scar? (anag)" , "swift and incisive?" , "Relating to operations" .)
