In some languages, possessives are formed from nouns or noun phrases. In English, this is done using the ending -'s, as in Jane's, heaven's, the boy's, those men's, or sometimes just an apostrophe, as in workers', Jesus', the soldiers'. Note that the ending can be added at the end of a noun phrase even when the phrase does not end with its head noun, as in the king of England's; this property inclines many linguists towards the view that the ending is a clitic rather than a case ending (see below, and further at English possessive).
