Force into an inadequate space in onshore hotel, strangely (8)
I believe the answer is:
shoehorn
'force into an inadequate space' is the definition.
(I've seen this before)
'onshore hotel strangely' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet).
'strangely' indicates anagramming the letters.
'onshore'+'h'='onshoreh'
'onshoreh' anagrammed gives 'SHOEHORN'.
'in' acts as a link.
(Other definitions for shoehorn that I've seen before include "Force (in Oxford?)" , "What wife too big for her boots may need" , "to make output of last worker yield more" , "A fitting device" , "Aid to squeezing foot into footwear" .)
