Side by side, having run into a depraved individual (7)
I believe the answer is:
abreast
'side by side' is the definition.
(synonyms)
'run into a depraved individual' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'into' is an insertion indicator.
'depraved individual' becomes 'beast' (beast is a kind of individual. I am not sure about the 'depraved' bit.).
'a'+'beast'='abeast'
'r' put into 'abeast' is 'ABREAST'.
'having' is the link.
Can you help me to learn more?
(Other definitions for abreast that I've seen before include "Side by side; keeping pace" , "Level or keeping pace with" , "Side by side - in the picture" , "Familiar" , "Well-informed" .)
