A Great Deal Of
This phrase is more formal and typically used with uncountable nouns (e.g., information, time, money).

This is a versatile quantifier suitable for both countable and uncountable nouns. It works in formal and informal contexts.
- There are a lot of students in the classroom. (countable)
