Prepositions: Across vs. Through

Hi there!

As I told you, here you have some extra resources in order to fully understand the difference between "across" and "through". First of all, let's watch this video, it's very illustrative!

Besides, the following image will help you to notice the difference between them:

Finally, here you have a written explanation in case you need further information about them:

a. Movement: When we talk about movement from one side to another but ‘in something’, such as long grass or a forest, we use through instead of across:

- I love walking through the forest. (through stresses being in the forest as I walk)

- When my dog runs through long grass, it’s difficult to find him. (through stresses that the dog is in the grass)

b. Time: When referring to a period of time from start to finish, American English speakers often use through where British English speakers say from … to/till …:

- The office is open Monday through Friday, 9 am–5 pm. (preferred British form: from Monday to Friday)

I hope you find this useful. See you in class!
