I've seen many times that some nouns are used with and without measure words. Is it optional to use measure words with certain words?
The most notable ones I have come across,
Is the measure word 个 before the word 星期 optional?
I guess, I've seen the word 小时 with the measure word 个 somewhere else. Is it optional to use 个 before 小时?
- And the last one, which one is correct? Or, Are they both correct?
Finally, is there a so-called "optional measure word" in Chinese?
