This word seems like an adjective but is actually a noun. כל is used in three different ways:
- It can be a substantive in which case it is functioning as a noun and means “everyone”, “everything”, or “all”.
- It can be in construct with an articular noun in which case it means “all of” or “the whole of”.
- It can be in construct with an anarthrous noun in which case it means “every” or “each”.
