do they know that

This phrase is correct and commonly used in English.

This phrase is used to form a question in the present simple tense, asking if a group of people is aware of something.

Examples:

  • Do they know that we are coming over?
  • Do they know that the meeting has been rescheduled?
  • Do they know that you're leaving tomorrow?
  • Do they know that she won the competition?
  • Do they know that it's going to rain?

does they know that

This phrase is incorrect in English.


Alternatives:

  • do they know that
  • does he know that
  • does she know that
  • do you know that
  • do we know that
The correct phrase is "do they know that". In English, when using the auxiliary verb "do" to form questions in the present simple tense, we need to use the base form of the main verb (in this case, "know"). The subject pronoun "they" is plural, so it requires the plural form of the verb, which is "do".
