English accessing castle, tipsy — is one hammered? (7)
I believe the answer is:
celesta
'one hammered?' is the definition.
I can't tell whether this definition defines the answer.
'english accessing castle tipsy' is the wordplay.
'english' becomes 'E' (abbreviation).
'accessing' is an insertion indicator (inserted letters gain access).
'tipsy' indicates an anagram.
'castle' is an anagram of 'celsta'.
'e' put inside 'celsta' is 'CELESTA'.
'is' is the link.
Can you help me to learn more?
(Other definitions for celesta that I've seen before include "one giving out notes" , "Keyboard percussion instrument giving a bell-like sound" , "a bunch of keys?" , "Musical instrument" , "Play this" .)
