Amateur; secular (3)
I believe the answer is:
lay
I believe this is a double definition.
'amateur' is the first definition.
(similar in meaning)
'secular' is the second definition.
(synonyms)
(Other definitions for lay that I've seen before include "in which hens regularly produce eggs?" , "Stake (a bet); song" , "Air" , "Non-clerical, amateur" , "Put down (in position)" .)
