What is conventional syntax?

Answer 1

Conventional Syntax refers to how language is typically used.

For example, in Standard English you would not say, "Y'all ain't goin' down ta tha hollir a-fishin' today, are ya's?" While this sentence would be fine in the hard-core Appalachian dialect, it would not be accepted in the Standard English dialect. You would, instead, say "You all aren't going fishing in the valley today, are you?"

In other words, Conventional Syntax refers to the way people typically put things together in a given dialect--the order certain parts of speech go in, the type of vernacular variations used--the systematic ruled which govern conventional usage of a dialect.
