English — Articles for generalization
English generalizes about a whole class in three ways: a tiger, tigers and the tiger. All three can mean “tigers in general”, but they frame the class differently and are not always interchangeable.
How it works
A tiger presents any single representative of the class (A tiger has stripes = pick any one). The bare plural tigers is the everyday, most natural generic (Tigers are endangered). The tiger treats the class as one abstract whole and sounds formal or scientific (The tiger is native to Asia). The is also used generically for inventions and instruments: the computer, the piano.
Examples
| Form | Type / use | Example |

| tigers | Generic — the whole class (most natural, everyday) | Tigers are endangered. |
| the tiger | Generic — the species as an abstract whole (formal, scientific) | The tiger is native to Asia. |
| the tiger | Specific — a particular known one (not generic) | The tiger at the zoo is asleep. |
| the computer | Generic — an invention / device type | The computer transformed the office. |
| the piano | Generic — a type of musical instrument | She plays the piano. |
Good to know
The + plural usually refers to a specific group, but definite plurals can also be generic in suitable contexts, as in The dinosaurs are extinct. For everyday general statements use the bare plural (Tigers are endangered). Generic the + singular is limited to certain countable class nouns, especially names of species and inventions; it cannot refer to one unknown individual out of the blue.
