Family welcoming European with no record of offending (5)
I believe the answer is:
clean
'no record of offending' is the definition.
I can't tell whether this defines the answer.
'family welcoming european' is the wordplay.
'family' becomes 'clan' (clan can mean a large family).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'european' becomes 'E' (abbreviation e.g. EU).
'clan' going around 'e' is 'CLEAN'.
'with' is the link.
Can you help me to learn more?
(Other definitions for clean that I've seen before include "Clear (of drugs)" , "Squeakily hygienic?" , "Unsoiled" , "Carrying no illegal drugs" , "Unspoiled" .)
