Usage of 'else' as adverb or conjunction

[Barman]

I learnt that Else is an adverb, not a conjunction.Therefore, please tell me whether the following sentences are correct.

1) Hurry up, else you will miss the train. ( used as a conjunction )

2) Hurry up, or else you will miss the train. ( used as an adverb )

1) Hurry up, else you will miss the train.

2) Hurry up, or else you will miss the train.

There may be a case for reclassifying "else" as a coordinator (your conjunction), where it would be in competition with "or". But it does not normally occur in clauses except with "or", as in 2), so it might be difficult to justify.

In 2) "else" expands the second coordinate: [Hurry up] [or else you'll miss the train],

"Else" is optional here in that it can be freely dropped with no loss of grammaticality. For this reason "or else" can't be considered a complex adverb.

The above is based on modern grammar. Traditional grammar may say otherwise.

Sentence one is grammatical but archaic in American English (and, I think, in other varieties). You can safely forget about that usage.
