Observe home has something to write on (7)
I believe the answer is:
notepad
'something to write on' is the definition.
I can't judge whether this defines the answer.
'observe home' is the wordplay.
'observe' becomes 'note' (synonyms).
'home' becomes 'pad' (pad can mean a person's home).
'note'+'pad'='NOTEPAD'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for notepad that I've seen before include "Block of writing paper; computer" , "Memo-block" , "Place for recording" , "Item to write on" , "Block writer might have" .)
