Kenny’s outside cutting turf up (7)
I believe the answer is:
skyward
'up' is the definition.
(similar in meaning)
'kenny's outside cutting turf' is the wordplay.
'outside' says to hollow out the word (remove centre letters).
'cutting' is an insertion indicator (some letters cut their way into a word).
'turf' becomes 'sward' (synonyms).
'kenny' with its centre taken out is 'ky'.
'ky' going inside 'sward' is 'SKYWARD'.
(Other definitions for skyward that I've seen before include "from the ground?" , "Up to the heavens" .)
