It uses rhythm and pitches to make consonance, a pleasant timbre, or in other words to make a good sound.

Essentially, the word “blackberry” (as you might guess) came from our ancestors looking at a berry-like fruit that was black, and deciding on a simple name for it. The word “black” comes from the Old Norse word for the color, which was “blakkr.” This developed into “blaec” in Old English.
