• Many nouns formed with -ity are uncountable; those that are countable form their plurals in -ities.
• Final -e is dropped before adding this suffix.
• Pronunciation:
  • The addition of -ity to an adjective results in a shift of stress to the antepenultimate syllable; that is, words in -ity are stressed on the last syllable before the -ity, even in cases where this syllable is part of another suffix (as in words in -ability and -icity). Further, this shift typically results in a change in vowel quality; compare, for example, real and reality, where the sound [æ] in the second word is not present in the first. These vowel quality changes are usually consistent with the spelling of both forms — note that the letter <a> in the second word is present in the first — but sometimes spelling changes are seen, as with the suffix -ous, which when it combines with -ity produces the suffix -osity.
  • While a final -c is pronounced [k], before -ity it becomes [s]; compare, for example, elastic and elasticity.

• -ability, -ibility

• -ness, -hood, -ship, -itas, -itude, -th, -ia, -itia, -ability, -ibility, -icity, -osity, -ous, -ose
