Can "thử" be used in this sense? In my family it's generally used to talk about trying food.
Tôi thử cô ấy would mean "I tried her" lol.
I understand that, what I meant is if there isn't another word meaning "to strive" that could be used in place of "thử" with all other words remaining the same (so something like: "Tôi ___ tìm hiểu cô ấy"
There's cố gắng which means to try/endeavour to.
