Tips

Place the Apostrophe

  1. Joint relation: one office shared by two owners. Base plural: pilots. Possessive: pilots’. Owned head: office.
  2. Pilot’s would mean one pilot; pilots has number but no written possessive marker; pilots’s adds an extra possessive s to a regular plural already ending in s.
