It's said in making appeals (6)
I believe the answer is:
please
'it's said in making appeals' is the definition.
I can't judge whether this definition defines the answer.
'it's said in making appeals' is the wordplay.
I cannot quite understand how this works, but
'appeals' could be 'pleas' (plea is a kind of appeal) and 'pleas' is present in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for please that I've seen before include "if you don't mind" , "Gratify or ask nicely" , "Gratify as by a sleep" , "Like" , "Cause to feel happy" .)
