"Have with" as a phrasal verb
Solution 1:
It is not considered a phrasal verb in OALD (see entries n° 1, n° 26); however, the meaning of "have" in this combination being "to carry along","to be with", which has apparently little to do with the basic idea of "possession" or "being associated to", this verb could be considered a phrasal verb. The difference could be that most lexicographers can still make out in the meaning "to be with" the idea of "being associated to", whereas some, as those from Merriam-Webster can't. It is extremely difficult to analyse such semantic relations sometimes.
