| There
are currently approximately 5,000 languages in the world. Many of
these languages are quickly disappearing and are being replaced by some of
the languages of commerce marked on the map. English is
currently the most important language of commerce. |
All
languages have ways of indicating what function each word serves in a
clause.
In many languages, these functions (case, number, gender) are indicated by morphemes that are added to the words. In English, the
function of each word is indicated by its word order in the clause. |
