Born in boring equine facility (6)
I believe the answer is:
stable
'equine facility' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'born in boring' is the wordplay.
'born' becomes 'b' (abbreviation next to the year of someone's birth).
'in' means one lot of letters goes inside another.
'boring' becomes 'stale' (I've seen this in another clue).
'b' inserted into 'stale' is 'STABLE'.
Can you help me to learn more?
(Other definitions for stable that I've seen before include "Horse barn" , "Firmly fixed - home for horse" , "Well-balanced and steady" , "Steady in the horse-house" , "Where horses are kept" .)
