Protected feet getting hot in turf (4)
I believe the answer is:
shod
'protected feet' is the definition.
Although both the answer and definition are past participle verbs, I cannot see how one could define the other.
'hot in turf' is the wordplay.
'hot' becomes 'h' (abbreviation eg on taps).
'in' means one lot of letters goes inside another.
'turf' becomes 'sod' (synonyms).
'h' going inside 'sod' is 'SHOD'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for shod that I've seen before include "with hooves protected?" , "Equipped with shoes" , "Like a horse that's been to a farrier" , "Wearing shoes" , "Not with bare feet" .)
