Certain individual words do possess more pitch, more radiance, more shazam! than others, but it's the way words are juxtaposed with other words in a phrase or sentence that can create magic. Perhaps literally. The word "grammar," like its sister word "glamour," is actually derived from an old Scottish word that meant "sorcery." When we were made to diagram sentences in high school, we were unwittingly being instructed in syntax sorcery, in wizardry. We were all enrolled at Hogwarts. Who knew?
