The (4) (The giraffe/the telephone/the piano etc.;the + adjective)

   
    A. Study these sentences:
  * The giraffe is the tallest of all animals.
  * The bicycle is an excellent means of transport.
  * When was the telephone invented?
  * The dollar is the currency (= money) of the United States.
  In these examples, the... does not mean one particular thing. The giraffe one particular type I animal, not one particular giraffe. We use the (+ a singular countable noun) in this way to talk about a type of animal, machine etc.
  In the same way we use the for musical instruments:
  * Can you play the guitar?
  * The piano is my favourite instrument.
  Compare a:
  * I'd like to have a guitar.
  * We saw a giraffe at the zoo.
  Note that we use man (= human beings in general/the human race) without 'the':
  * What do you know about the origins of man? (not 'the man')
    B. The + adjective
  We use the + adjective (without a noun) to talk about groups of people, especially:
  the young  the old  the elderly  the rich  the poor  the unemployed  the homeless  the sick  the disabled  the injured  the dead
  The young = young people, the rich = rich people etc.:
  * Do you think the rich should pay more taxes to help the poor?
  * The homeless need more help from the government.
  These expressions are always plural in meaning. You cannot say 'a young' or 'an unemployed'. You must say 'a young man', 'an unemployed woman' etc. Note also that we say 'the poor' (not 'the poors'), 'the young' (not 'the youngs') etc.
    C. The + nationality
  You can use the with some nationality adjectives to mean 'the people of that country'. For example:
  * The French are famous for their food. (= the people of France)
  * Why do the English think they are so wonderful? (= the people of England) In the same way you can say:
  the Spanish  the Dutch  the British  the Irish  the Welsh
  Note that the French/the English etc. are plural in meaning. You cannot say 'a French/an English'. You have to say 'a Frenchman/an Englishwoman' etc.
  You can also use the + nationality words ending in -ese (the Chinese/the Sudanese etc.):
  * The Chinese invented printing.
  These words can also be singular (a Japanese, a Sudanese).
  Also: the Swiss/a Swiss (plural or singular)
  With other nationalities, the plural noun ends in -s. For example:
  an Italian  a Mexican  a Scot  a Turk  (the) Italians  (the) Mexicans  (the) Scots  (the) Turks
