Quantity expressions with 'de'
When learning French, you quickly get used to putting an article in front of every noun. If you want some bread, you ask for du pain. If you want some apples, you ask for des pommes. However, a major exception occurs when you specify the quantity.
If you use an expression of quantity like beaucoup, trop, or un peu, the article vanishes. You are left with a simple de to connect the quantity to the noun.
Adverbs of quantity are followed immediately by a bare de, which becomes d' before a vowel or mute h. The partitive articles like du, de la, and des are completely dropped. You will never say beaucoup du pain, only beaucoup de pain.
This rule applies to both large and small quantities. Words like peu, un peu, un petit peu, and plus behave exactly the same way. Simply place de right after them.
The question word combien also triggers this rule, whether you are asking about an uncountable noun or a countable one. The adverb suffisamment does the same thing.
There is a catch. The article is only dropped for general, unspecified quantities. If you are talking about a specific, defined group, the definite article stays. For example, if you say "a lot of the books I read", you are specifying exactly which books you mean. In that case, de combines with les to become des: beaucoup des livres que j'ai lus.
As long as you are talking about general amounts, stick to the bare de. Other common quantity words, such as moins de (less of) and autant de (as much of), also follow this bare de rule.
Whenever you use an expression of general quantity like beaucoup, trop, or combien, drop the partitive or definite article and follow the word directly with a bare de or d'.
