• The plural possessive -s’ can be distinguished from the possessive marker -' on nouns that terminate in -s and from the possessive marker -'s (which see). Whether they are pronounced identically or differently varies between idiolects. The BBC prescribes the following distinction:[1] (a) Dickens novel and Dickens’ novel /dɪkɪnz nɒvəl/, Dickens’s novel /dɪkɪnzɪz nɒvəl/; princess’s and princesses’ /pɹɪn.sɛs.ɪz/; i.e. adding bare ’ does not change pronunciation. Some speakers, however, may pronounce one or both as /ɪz/, i.e. Dickens’ as /ˈdɪkɪnzɪz/, princesses’ as /pɹɪn.sɛs.ɪz.ɪz/, and e.g. boys’ as /bɔɪzɪz/ (instead of the more common /bɔɪz/).
• Traditionally, the possessives of classical and Biblical names ending in s, such as Archimedes and Jesus, were written without a final “s”, i.e. the possessives were formed using bare ': Archimedes’ Principle (the principle of Archimedes), Jesus’ disciples (the disciples of Jesus). This may or may not be be distinguished from -'s in pronunciation; see -'s for more. The American Heritage Dictionary (under the entry "possessive") extends this to other words or names having at least two syllables, such as Dickens' or witness'. In modern English, the practice in fact extends to all names ending in s, i.e. both "Chris' recipe" and "Chris's recipe" are found:

    Sam, the Lebanese milk bar man, followed Chris's recipe.

  • 2012, Jack Edward Shay, Bygone Binghamton: Remembering People and Places of the Past, →ISBN:

    That was Chris' recipe.

• -’ may also be used on nouns ending in an s sound (i.e., not necessarily ending in the letter s).
