Pressed on and I got angry about (6)
I believe the answer is:
ironed
'pressed' is the definition.
(ironing is a kind of pressing)
'and i got angry about' is the wordplay.
'and' becomes 'n' (common abbreviation for 'and').
'got angry' becomes 'roed' (I can't explain this - if you can you should believe this answer much more).
'about' is an insertion indicator.
'i'+'roed'='iroed'
'n' put inside 'iroed' is 'IRONED'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for ironed that I've seen before include "Removed creases" , "Smoothed the cloth with heat" , "Smoothed with domestic device" , "Smoothed cloth with flatbased implement" , "Smoothed out wrinkles" .)
