"The" is very much a sticking point for native speakers of languages that don't have a similar construct; i.e. a Spanish speaker wouldn't likely have trouble with it, but a Japanese or Korean speaker more likely would. The issue is 'a' vs 'the' vs nothing: he went to the school he went to a school he went to school All have very different meanings - "the" is effectively an adjective describing the specificity of the noun. The first describes a specific school, the second describes some not-yet-defined school, the third describes an abstract concept. 'Chocolate' is another example of this, where the issue extends to the use of words like 'some', 'how many', and 'how much' (countable vs. uncountable quantities). Even if a person understands these concepts, it's still difficult to propagate it through a sentence so that everything type-checks (subject-verb agreement, etc), especially if you're coming from a language that doesn't have this kind of redundancy. It gets even harder with hypotheticals, where sometimes one might switch between both singular/plural and non-specific/specific mid sentence, all while English lacks gender-neutral singular third-person pronouns. On top of this there are cases where the use of one over the other really just comes down to philosophy (whether native speakers of a language consider something distinct, concrete, or countable, or not). Similar issues come up with prepositions - which preposition goes with which verb differs even when describing the same concept in two very similar languages. (Best example I can think of at the moment is that in Japanese, people say "I bought it to her" instead of "I bought it for her"; I know English<->Spanish has similar issues, but my Spanish is rusty)
