"get along" er "git along" or "go along" (does vehicular usage matter?)?

Why is that individual (quote attached as screenshot for evidence, servant turned their back to face away before issuing the command, to/for the conductor to drive) saying "get along" and not "go along"?

Is the carraige/stagecoach the reason for why they're saying get instead of go?

Strangely wording at https://en.wiktionary.org/wiki/get_along does not by definition, but https://en.wiktionary.org/wiki/git_along does by definition, and https://en.wiktionary.org/wiki/go_along definitely says "to move along or proceed".

The actual wording from reading/watching Jane Eyre (BBC) steaming from Hulu is "Get along!".

Is that just how they actually spoke back then, did the editor/transcriber/writer/subtitler/captioner act correctly or make a mistake there, did the speaker slur the command "get" with "git" (like saying "ride") because of the horses present or being around horses so much, was rider/conductor/speaker's social class/status relevant to the usage, or were other factors defining that as passing for actual functional English?

If the vehicle moved, that means the code I mean language worked?

Solution 1:

There is no mystery. "Get" is the imperative, and "along" is its adverb complement. "Get along." is still used (at least in BE) as an order commanding, usually an animal, to move. "Get" is approximately the same as "start to move."

"Go along" is not idiomatic as a command.

"Git" is a dialect version of "get".

The OED gives the non-imperative version that is used for humans:

to get along

  1. intransitive. a. To proceed, progress, advance. Also (frequently in the progressive): to depart, go on one's way, get going. Also formerly: †to go in company with.
