“miss out on love from their family” -
“lack of” has been corrected by Alan and switched to “miss out on”.
Is there any difference between them?
.
Miss out on is a phrasal verb. Lack of is a noun+preposition.
Miss out on means to fail to experience; to lose an opportunity. Lack of means a condition of unavailability or absence (the verb lack means be without).
Does that help?
.
Absolutely. Thankee Mr. Micawber.
