Just communicate with phone daughter left out (9)
I believe the answer is:
impartial
'just' is the definition.
(associated in meaning)
'communicate with phone daughter left out' is the wordplay.
'communicate with' becomes 'impart' (impart can mean to communicate or pass on. I am not sure about the 'with' bit.).
'phone' becomes 'dial phone' (dial phone is a kind of phone).
'daughter' becomes 'd' (genealogical abbreviation).
'left out' suggests deleting specific letters.
'dial' with 'd' taken out is 'ial'.
'impart'+'ial'='IMPARTIAL'
Can you help me to learn more?
(Other definitions for impartial that I've seen before include "Treating all rivals equally" , "Unbiased" , "Showing lack of favouritism" , "not taking sides" , "Fair, unprejudiced" .)
