Lin was going around to her husband’s family (2-4)
I believe the answer is:
'her husband's family' is the definition.
I can't tell whether this definition defines the answer.
'lin was going around' is the wordplay.
'going around' indicates anagramming the letters.
'linwas' with letters rearranged gives 'IN-LAWS'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for in-laws that I've seen before include "A person's relatives by marriage" , "Relations by marriage" , "Spouse's relations" , "Christmas is when you might bid them welcome" , "Relatives by marriage 2-4)" .)
