Articles
The article a/an is usually dropped after sort of, kind of and type of, but structures with articles are possible in an informal style.
- That’s a funny sort of (a) car.

Singular and plural; these sort of, etc
When we are talking about one sort of thing, we can use sort of, kind of or type of followed by a singular noun.
- This sort of car is enormously expensive to run.
- I’m interested in any new type of development in computer science.
Singular sort of, kind of and type of can also be followed by plural nouns, especially in an informal style.
- I’m interested in any new kind of developments …
Plural demonstratives (these and those) can also be used.
- These sort of cars are enormously expensive to run.
- Do you smoke those kind of cigarettes?
This structure (these sort of, etc) is often felt to be incorrect, and is usually avoided in a formal style. This can be done by using a singular noun (see above), by using plural sorts/kinds/types, or by using the structure … of this/that sort/kind/type.
- This sort of car is …
- These kinds of car(s) are …
- Cars of that type are …
