High ground suiting the sick in outer Hastings (5)
I believe the answer is:
hills
'high ground suiting' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'the sick in outer hastings' is the wordplay.
'the sick' becomes 'ill' (I've seen this before).
'in' means one lot of letters goes inside another.
'outer' says to hollow out the word (remove centre letters).
'hastings' with its centre removed is 'hs'.
'ill' going into 'hs' is 'HILLS'.
Can you help me to learn more?
(Other definitions for hills that I've seen before include "High terrain" , "Elevations of land" , "Mounts" , "See 7" , "Heights; tors" .)
