It’s easy for one to get left in front (6)
I believe the answer is:
facile
'it's easy' is the definition.
(synonyms)
'one to get left in front' is the wordplay.
'one' becomes 'i' (roman numeral).
'to get' says to put letters next to each other.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'front' becomes 'face' (face is a kind of front).
'i'+'l'='il'
'il' inserted inside 'face' is 'FACILE'.
'for' acts as a link.
(Other definitions for facile that I've seen before include "Oversimplified" , "Easy but glib" , "Over-simple, superficial" , "Arrived at without due care or effort" , "A piece of cake" .)
