Patrón
verb + 得了 (can) / verb + 不了 (can’t)
Here 了 is read liǎo, not le. Verb + 不了 means circumstances make the action impossible (去不了 = can’t go), or the amount is too much to finish (吃不了). Verb + 得了 is the positive “can manage.”
明天我有事，去不了。
When to use Verb + 得了 / 不了 for “Can” and “Can’t Manage”
Put 得了 or 不了 right after the verb. The 了 here is pronounced liǎo and keeps its tone; 得 and 不 are light: 去得了 (qù de liǎo), 去不了 (qù bu liǎo). It has two main meanings. First, whether the action can happen at all: 明天我有事，去不了 (I can’t go). Second, whether a quantity can be finished: 菜太多了，我一个人吃不了. The negative 不了 is much more common than the positive; 得了 appears mostly in questions and reassurances.
菜太多了，我一个人吃不了。
There’s too much food; I can’t finish it by myself.
