Correct Usage 13 – Apostrophe

The Correct use of Apostrophe (‘)

The apostrophe has two functions.

  1. As in “Ms Pareker’s symptoms.” (Whose? – Possession)
  2. As in “He hasn’t recovered yet.” (“Has + not” – Contraction)

Possession

  1. Charlie and Lola’s new room. (the room belongs to both Charlie and Lola, so, we use apostrophe with the last name)
  2. Mr William’s condition has worsened.
  3. Ms Williams’ daughter is upset about her mother’s behavior.
  4. Alzheimer’s Disease.
  5. Little Alice’ diagnosis has been confirmed.
  6. The boys’ breathing has not improved yet.
  7. Most Children’s sense of hygiene has improved over the month.
  8. Its, hers, yours, ours (there is no apostrophe before the possessive –s with pronouns)

Contractions

The apostrophe is used with contractions (short-forms) and is placed at the spot of the omitted letter(s).

I + am → I + a + m → going to remove “a” → I + am → I + ‘+m → I’m

  • I am = I’m
  • You are = you’re
  • He is = he’s
  • She is = she’s
  • It is = it’s
  • We are = we’re
  • They are = they’re
  • Do not = don’t
  • Does not = doesn’t
  • Cannot = can’t (cannot is written as one word)
  • Should not = shouldn’t
  • Could not = couldn’t
  • Shall not = shan’t
  • Will not = won’t
  • I have = I’ve
  • I had, I would, and I should = I’d
  • I will and I shall = I’ll

Attention!

If a word ends in S or CE, the apostrophe come after the s / ce sound.

  • Mr Moses’s house → Mr Moses’ house
  • Ms Alice’s condition → Ms Alice’ condition
