Dear Teachers,

I would like to know the difference between "open" and "be open". As far I as I know, "open" can be in both verb & adjective form. For example....

  • The application will open

  • The application will be open
Which sentence should be the correct one? If possible, would you please give other examples for me to have a better understanding.

Many thanks!! Emotion: smile
Hi,

I would like to know the difference between "open" and "be open". As far I as I know, "open" can be in both verb & adjective form. For example....

  • Which sentence should be the correct one? If possible, would you please give other examples for me to have a better understanding.

    You could start by considering these examples.

    Tom has a store.

    Tomorrow, he will open his store at 9am.

    His store will be open from 9am to 6pm.

    He will close his store at 6pm.

    Do you have any questions about these sentences?

    Best wishes, Clive

Hi,

You're welcome. You might like to try to write and post a few sentences, if you still have any doubts on this topic.

Oh.. Jim.

I think you made a nice thread regarding complicated use of 'open' which can be considered as my exam's questionEmotion: smile

It's good to categorise each use: active and passive(verb)/ predicative and attributive(adj)

This should be at my disposal in case this appears on my exam.

It's good to know that open in Attributive use does not have '-ed' but just a normal form.(To me, the opened window, opened bottles and the opened door sound better, but now I've just come to know I should get out of misconception.)
