Quantifiers are adjectives and adjectival phrases that give approximate or specific answers to the questions "How much?" and "How many?" Education First
We use the quantifiers much, many, a lot of, lots of to talk about quantities, amounts and degree. We can use them with a noun (as a determiner) or without a noun (as a pronoun). Cambridge Dictionary
What is the part of speech of "quantifiers"? Are they adjectives or determiner? Or both together?

There is no universal convention on the parts of speech in English, except perhaps that linguists dislike the term part of speech (they prefer terms like lexical category or word class). Consider the following:
The case has been made that determiners should be considered a separate class of words, just as pronouns are distinct from nouns. After all, it is a closed set of words which behaves differently from adjectives: they cannot be stacked, they cannot be graded, they cannot be intensified. They have a distinctive purpose in a sentence. Modern textbooks seem to agree, including all three noted above. Note that the Education First website also recognizes this distinction in the organization of its site.
