Difference between the suffixes "-titude" and "-titute"

Solution 1:

-tude : is a common suffix used to form abstract nouns:

  • syllable formed when the word-forming element -ude, making abstract nouns from adjectives and participles, is fixed to a base or to another suffix ending in -t or -te; from French -ude, from Latin -udo (stem -udin-). The equivalent of native -ness. (words ending with -tude)
  • -tute or -ute are not really suffixes with a specific connotation! (words ending with -tute)
