This is a dialect that famously uses different vocabulary and meanings, some of which may be archaic, such as “britches” (trousers), “poke” (bag), “sallet” (salad, as in a poke-sallet, of pokeweed rather than bags!), “afeared” (afraid), “fixin” (getting ready, as in “I’m fixin to do something”), “allow” (suppose, as in “I’ll allow as how I’ll go over yander for a leetle spell”).
