Does this 'flexibility' mean "able to adapt to changing circumstances" and also "able to stretch greatly, like a gymnast or martial artist"? Or is it just the first definition?
It is mostly used with the first definition but I saw it used in the second one too (as in "sự linh hoạt của cơ thể")
Flexible marked wrong why
Flexibility is not the same as flexible.
Flexibility is a noun and flexible is an adverb.
Flexibility (n) : sự linh hoạt, sự uyển chuyển, sự mềm dẻo. Flexible (adj) : linh hoạt, dễ uốn nắn.
