Stuff is one of our language’s most adorable multipurpose words. It is short but packed with useful applications. It is balanced: two consonants—one vowel–two consonants, which appeals to all those symmetry buffs. It offers a mixture of sounds, beginning with the soft “s” sound and ending with the always gentle “double-f” sound, as in fluff and puff. It also uses the staccato, tough-sounding “t.” You would be hard pressed to find a much more useful word that is so much fun to say.
