Share opinion with one occupying cleaner seat at table (4,5)
I believe the answer is:
side chair
'seat at table' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'share opinion with one occupying cleaner' is the wordplay.
'share opinion with' becomes 'side' (I am not sure about this - if you are sure you should believe this answer much more).
'one' becomes 'I' (Roman numeral).
'occupying' means one lot of letters goes inside another (inserted letters occupy or enter the word).
'cleaner' becomes 'char' (charwoman is a type of cleaner).
'i' put into 'char' is 'chair'.
'side'+'chair'='SIDE CHAIR'
Can you help me to learn more?
