Nicola, awfully cold and saying little (7)
I believe the answer is:
laconic
'saying little' is the definition.
(I've seen this before)
'nicola awfully cold' is the wordplay.
'awfully' is an anagram indicator.
'cold' becomes 'c' (eg on taps).
'nicola' with letters rearranged gives 'laconi'.
'laconi'+'c'='LACONIC'
'and' acts as a link.
(Other definitions for laconic that I've seen before include "Succinct in speech" , "Terse in conical way" , "Saying little" , "Succinct, terse" , "Spartan" .)
