Spotted photo's source that is obvious (7)
I believe the answer is:
piebald
'spotted' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'photo's source that is obvious' is the wordplay.
'source' suggests taking the first letters (source can mean a beginning or origin).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'obvious' becomes 'bald'.
The initial letter of 'photos' is 'p'.
'p'+'ie'+'bald'='PIEBALD'
Can you help me to learn more?
(Other definitions for piebald that I've seen before include "Having contrasting patches of colour" , "Two-coloured (horse)" , "Bicoloured" , "Of horse, with patches of white and dark colour" , "Marked in two different colours, especially black and white" .)
