Hope a bit of sun appears in most of country (6)
I believe the answer is:
prayer
'hope' is the definition.
(I have seen 'Earnest hope ' mean 'prayer' so perhaps 'hope' could also mean 'prayer')
'a bit of sun appears in most of country' is the wordplay.
'a bit of sun' becomes 'ray' (I've seen this in another clue).
'appears in' indicates putting letters inside.
'most of' means to remove the last letter.
'country' becomes 'Peru' (Peru is an example).
'peru' with its last letter taken away is 'per'.
'ray' going into 'per' is 'PRAYER'.
(Other definitions for prayer that I've seen before include "Supplication [ital]" , "Plea, invocation" , "Reverent petition to a deity" , "Request (maybe to God)" , "Entrety or supplication" .)
