Provides checks for each non-expert (9)
I believe the answer is:
layperson
'non-expert' is the definition.
I can't tell whether this definition defines the answer.
'provides checks for each' is the wordplay.
'provides' becomes 'layson' (I've seen this before).
'checks' means one lot of letters goes inside another (inserted letters are checked or controlled).
'for each' becomes 'per' (per person).
'layson' placed around 'per' is 'LAYPERSON'.
Can you help me to learn more?
(Other definitions for layperson that I've seen before include "one of his flock maybe" , "Amateur" , "Not an expert" , "parishioner?" , "Non-specialist" .)
