Adviser keeps son away from others (5)
I believe the answer is:
aside
'away from others' is the definition.
I can't tell whether this defines the answer.
'adviser keeps son' is the wordplay.
'adviser' becomes 'aide'.
'keeps' means one lot of letters goes inside another.
'son' becomes 's' (genealogical abbreviation for son).
'aide' going around 's' is 'ASIDE'.
Can you help me to learn more?
(Other definitions for aside that I've seen before include "kept in reserve" , "Actor's remark for the audience alone" , "Line spoken to the audience of a play" , "Actors comment to his audience" , "Separately" .)
