PSA: "dialectal", not "dialectical"

Syntactical Syntactic and phonological differences between two dialects are known as dialectal variation. Dialectics is the way of arriving at a truth by considering opposing viewpoints. Dialectical approaches may involve dialog and debate. I've seen many here recently using the latter term. I recall that term being used back in grad school only to discover more recently that the term was used incorrectly.
