Hi Ciesielski! I’m not sure I understand this because I don’t know where you’ve read ‘travel’ is usually a verb. It would have to depend on context. In scientific texts it’s often a verb. For example light travels at a speed of 299 792 458 m/s. In everyday speech though, it’s generally an (uncountable) noun. Hope this helps.

It has been written: “In this videos you’ll learn that travel is usually an uncountable noun and that we don’t usually use it as a verb” and then we learn this:”The word ‘travel’ is usually a verb – an action – and it means to go from one place to another.”.

So glad you liked it Deepak Thanks for writing.
