Chinese Grammar learning: 可 + Adj (+ 了)
可 (kě) can be used to intensify an adjective, or to add emphasis to a verb. It is stronger than other modifiers, as 可 compares the speaker‘s expectations with the actual situation. The meaning of 可 is very reliant on context.
可 is generally used by Northern speakers and is informal, generally only used in spoken Chinese.
可 used to intensify an adjective
In these examples, 可 is used a bit like 很, as it is used to intensify an adjective:
这 只 小 狗 可 淘气 了！
哇，这 个 糖醋 里脊 可 好吃 了！
可 used to emphasize a verb
In these examples 可 is used a bit like 真, and used to emphasize a verb:
你 可 来 了!
你 可 别 喝 太 多 酒。
你 可 别 走！
话 可 不 能 这 样 说。
In two of the sentences above, 可 is used with 别, and sounds a bit like "don't even think about..." in English.
