So, I was just writing a sentence along the lines of "...the sales person will not enter the information....".
I went back and wrote it as "...the sales person will not enter the information...." to make sure we don't lose track of the key bit. If I were speaking that phrase, I would emphasize the 'not'. [I'm guessing there's a linguistic word describing how one stresses some important point in a sentence. I just don't know it.]
I also understand that not all languages have a grammatical construct such that negation is a separate word and/or used in that particular word order. Does that mean a language with "not" as a suffix stresses the suffix to underscore a point?
More generally, do all languages use what I'm calling "stress" or "emphasis" to underscore points? Is that the same thing as asking if all languages of some sort of tonality? Are there languages with zero stress in this regard but use some other means like word order or syntax or some other bit I can't even think of?
If this phenomenon is indeed universal, does that say something about the genetic proclivity for language? If not universal, does it suggest the opposite?
