GR-1 The conjunction “that”

In English, you can use the conjunction "that" to connect additional information (in a subordinate clause) to a main clause. You can use it after verbs such as “make sure”, “show” and “recommend”. Native English speakers often omit it when they speak quickly and this style is also found in writing. But this word helps the reader to understand where the main clause ends, and the subordinate clause starts. Because it can prevent ambiguity, try not to omit it.

This conjunction also helps with translation because, in many other languages, it is not possible to omit the equivalent word.

Examples:

Do not write: Make sure the valve is open.

WRITE: Make sure that the valve is open.

Do not write: The manufacturer recommends you prepare the mixture in an area with good airflow.

WRITE: The manufacturer recommends that you prepare the mixture in an area with good airflow.

Do not write: The gauge shows the reservoir is full.

WRITE: The gauge shows that the reservoir is full.
