Request met with certain satisfaction (8)
I believe the answer is:
pleasure
'satisfaction' is the definition.
(I know that satisfaction can be written as pleasure)
'request met with certain' is the wordplay.
'request' becomes 'plea' (plea is a kind of request).
'met' means one lot of letters go next to another.
'with certain' becomes 'sure' (synonyms. I am not sure about the 'with' bit.).
'plea'+'sure'='PLEASURE'
Can you help me to learn more?
(Other definitions for pleasure that I've seen before include "A repulse (anag.)" , "Feeling of enjoyment or satisfaction" , "Enjoyment, happiness" , "Delight, joy" , "A very desirable feeling" .)
