This is the 48th most frequent Chinese word.
可
"可" means "can," "may," or "able to."
Here, '可' is used as an intensifier to emphasize the degree of beauty.
这个风景可美了！
This scenery is really beautiful!
In this sentence, '可' stresses the extent to which the statement is true, adding emotional emphasis.
他可真一个有才华的人。
He is truly a talented person.
'可' serves as a conjunction, equivalent to 'but' in English, presenting a contrasting statement.
