Common Mistake: Missing Hyphen in '2 Family House'

One common mistake that people often make is forgetting to include a hyphen when writing phrases like '2 family house'. The correct way to write it is '2-family house', with a hyphen between the numeral and the word 'family'.

What is a Hyphen?

A hyphen is a punctuation mark (-) used to join words or parts of words together and form compound words or phrases. It is different from a dash, which is longer and used for different purposes.

Why is the Hyphen Important?

The hyphen is important because it helps to clarify the meaning of a word or phrase. In the case of '2-family house', the hyphen serves to connect the numeral '2' with the word 'family', indicating that these two elements should be read together as a single unit modifying the noun 'house'.


  • Incorrect: 2 family house
  • Correct: 2-family house

In the incorrect example above, the absence of the hyphen can lead to confusion or misinterpretation. It may be unclear whether '2 family' refers to two separate families or a specific type of housing unit. However, when the hyphen is included, as shown in the correct example, it is clear that '2-family' is a compound modifier describing the type of house.
