Beginner's question here.
If I understood correctly, all descriptive words in Mandarin can work both as an adjective and a "descriptive verb", which would be equivalent to the construction "to be + adjective" in English. If used as an adjective (i.e. accompanying the subject or object) the descriptive word must be followed by the 的 particle.
However, it seems that, in a simple affirmative sentence, the "descriptive verb" cannot be used directly after a personal pronoun, or as a standalone sentence with implied subject. Even though such construction is possible in questions or negative statements.
Here's a recap of what I (think I) know so far:
漂亮的女 - A beautiful woman
她漂亮吗? - Is she beautiful?
她不漂亮。- She is not beautiful.
她很漂亮。- She is beautiful. / She is very beautiful.
If I got it right, in the last example 很 does not mean necessarily "very". It can be as much a "filler word", that's to say, just a grammatical requirement for the affirmative sentence translated as "pronoun + be + adjective" in English. Is that so?
