Expression: miss out on

[moniker]

"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?

[Mister Micawber]

.
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?
