"The students are drawing the flag of Russia."

Translation: Các học sinh đang vẽ lá cờ của nước Nga.

Why not cái cờ?

[ForgetUmbrella]

"lá" is the more appropriate/specific classifier.

[StewartMM]

So 'là' is the classifier. What else does it apply to?

[vngdhuyen]

• lá thư: letter
• lá phiếu: ballot paper
• lá bài: playing card
• lá bùa: talisman
• lá gan: liver
• lá phổi: lung
• lá lách: spleen
• lá mía: pancreas

ps. lá, not là

[SergeyBey]

I wrote : Những học sinh đang vẽ cái cờ của nước Nga. But, duo told me that it's wrong, and that I need to put "lá" between vẽ and cờ. Anybody knows why?

[TehVanarch]

"lá" means "leaf" but as a counting word/classifier it's used for "sheet" like objects such as flags.
