Greenberg's linguistic universals

The American linguist Joseph Greenberg (1915–2001) proposed a set of linguistic universals based primarily on a set of 30 languages. The following list is verbatim from the list printed in the appendix of Greenberg's article "Some Universals of Grammar With Particular Reference to the Order of Meaningful Elements" in Universals of Language (1963) and "Universals Restated", sorted by context.
