Concealed single theologian in feathery layer? (6)
I believe the answer is:
hidden
'concealed' is the definition.
(I know that concealed can be written as hidden)
'single theologian in feathery layer?' is the wordplay.
'single' becomes 'i' (one).
'theologian' becomes 'DD' (Doctor of Divinity degree).
'in' means one lot of letters goes inside another.
'feathery layer?' becomes 'hen' (feathered bird which lays eggs).
'i'+'dd'='idd'
'idd' inserted within 'hen' is 'HIDDEN'.
(Other definitions for hidden that I've seen before include "Concealed, kept secret" , "Deliberately placed out of sight and hard to find" , "Concealed, recondite" , "Abstruse" , "Latent" .)
