Easily annoyed, bishop being pressed by two internationals on board (9)
I believe the answer is:
irritable
'easily annoyed' is the definition.
(I've seen this before)
'bishop being pressed by two internationals on board' is the wordplay.
'two internationals' can mean two substitutions for 'international'.
'bishop' becomes 'rr' (abbreviation for Right Reverend).
'being pressed by' is an insertion indicator (inserted letters are pressed or squeezed inside).
'international' becomes 'i' (abbreviation eg in IMF).
'international' becomes 'i' (abbreviation eg in IMF).
'on board' becomes 'table' (both can mean food. I am not sure about the 'on' bit.).
'i'+'i'='ii'
'rr' going into 'ii' is 'irri'.
'irri'+'table'='IRRITABLE'
Can you help me to learn more?
(Other definitions for irritable that I've seen before include "Testy" , "Easily annoyed" , "Peevish" , "Touchy" , "Tetchy" .)
