Build hotel by Yankee Stadium’s entrance? Irritation all round (8)
I believe the answer is:
physique
'build' is the definition.
(I know that build can be written as physique)
'hotel by yankee stadium's entrance? irritation all round' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'by' means one lot of letters go next to another.
'entrance?' indicates taking the first letters (I've seen 'entrance' mean this).
'irritation' becomes 'pique' (synonyms).
'all round' is an insertion indicator.
The initial letters of 'yankee stadiums' is 'ys'.
'h'+'ys'='hys'
'hys' going inside 'pique' is 'PHYSIQUE'.
(Other definitions for physique that I've seen before include "Person's build and muscular development" , "Constitution of the human body" , "Shape and size of a person's body" , "Bodily type, build, or constitution" , "Form" .)
