Love tucking into awfully tall beer, ok? (9)
I believe the answer is:
tolerable
'ok?' is the definition.
(thesaurus)
'love tucking into awfully tall beer' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'tucking into' means one lot of letters goes inside another.
'awfully' is an anagram indicator.
'tall'+'beer'='tallbeer'
'tallbeer' is an anagram of 'tlerable'.
'o' placed within 'tlerable' is 'TOLERABLE'.
(Other definitions for tolerable that I've seen before include "Acceptable" , "Passable" , "Mediocre" , "Fair" , "Adequate" .)
