[00:00:00]Fastly is not a word. So, we all know take an adjective like quick, add ly to it, it becomes quickly, which is an adverb, right? So, adjective plus ly becomes adverb, right?

[00:00:21]Yes, but not all the time.

[00:00:25]Here are five adverbs in which ly is actually wrong. So, if you want to say that someone came early, you don't say early.

[00:00:38]It's not a word. We say he came early.

[00:00:42]Same with late. We don't say lately because it would mean something different. It would mean recently. So, he came early, he came late. High and low.

[00:00:56]We say the plane flies high, not highly.

[00:01:00]Highly is something different. Again, it has a different meaning. If you mean distance, like how far up or down something is, it's high and low, not highly and lowly.

[00:01:12]Finally, fast.
