'somewhat heated' is the definition.
'warmed' can be an answer for 'heated' (I've seen this before). I am unsure of the 'somewhat' bit.

'west gets ready to fight' is the wordplay.
'west' becomes 'W' (abbreviation).
'gets' means one lot of letters go next to another.
'ready to fight' becomes 'armed' (I've seen this before).
'w'+'armed'='WARMED'

'the' is the link.

Can you help me to learn more?

(Other definitions for warmed that I've seen before include "Heated" , "given thermal treatment" , "gave enthusiasm" .)
