Managed my no-frills accommodation, full of bitterness (9)
I believe the answer is:
rancorous
'managed my no-frills accommodation full of bitterness' is the definition.
I can't judge whether this definition defines the answer.
'managed my no-frills accommodation' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'my' becomes 'cor' (both are expressions of surprise).
'no-frills' says to take the centre (edge letters or 'frills' are removed).
'accommodation' becomes 'house'.
The middle of 'house' is 'ous'.
'ran'+'cor'+'ous'='RANCOROUS'
Can you help me to learn more?
(Other definitions for rancorous that I've seen before include "Acrimonious" , "Resentful, bitter" , "Showing bitter resentment" , "spiteful?" .)
