A priest misled them suggesting it would be laid on? (7)
I believe the answer is:
applied
'them suggesting it would be laid on?' is the definition.
I can't judge whether this definition defines the answer.
'a priest misled' is the wordplay.
'priest' becomes 'pp' (I've seen this in other clues).
'misled' becomes 'lied' (I am not sure about this - if you are sure you should believe this answer much more).
'a'+'pp'+'lied'='APPLIED'
Can you help me to learn more?
(Other definitions for applied that I've seen before include "put to practical use" , "Administered" , "Employed" , "Put into practice or requested" , "Was relevant" .)
