Singer in a wooded hollow heard (5)

I believe the answer is:

adele

I'm a little stuck... Click here to teach me more about this clue!

'singer' is the definition.
(I've seen this before)

'a wooded hollow heard' is the wordplay.
'wooded hollow' becomes 'del' (I am not sure about this - if you are sure you should believe this answer much more).
'heard' becomes 'e' (I've seen this in other clues).
'a'+'del'+'e'='ADELE'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for adele that I've seen before include "Singer with albums titled 19, 21 and 25" , "girl" , "Performer" , "Female English singer-songwriter, b. 1988" , "Popular female singer" .)
