    In case or if

    In case or if


    Ann might phone tonight. I don't want to go out in case she phones. (= because it is possible she will phone)

    I'll draw a map for you in case you can't find our house. (= because it is possible you won't be able to find it)

    We use just in case for a smaller possibility:

    I don't think it will rain but I'll take an umbrella just in case. (= just in case it rains)

    Do not use will after in case. Use a present tense for the future

    I don't want to go out tonight in case Ann phones, (not 'in case Ann will phone')


    - In case is not the same as if. We use in case to say why somebody does (or doesn't do) something. You do something now in case something happens later.



    In case :


    • We'll buy some more food in case Tom comes.(= Perhaps Tom will come; we'll buy some more food now, whether he comes or not; then we'll already have the food //he comes.)
    • I'll give you my phone number in case you need to contact me.
    • You should insure your bicycle in case it is stolen.



    ·        We'll buy some more food if Tom comes. (= Perhaps Tom will come; if he comes, we'll buy some more food; if he doesn't come, we won't buy any more food.)

    ·        You can phone me at the hotel if you need to contact me.

    ·        You should inform the police if your bicycle is stolen.


    You can use in case (+ past) to say why somebody did something:


    • We bought some more food in case Tom came. (= because it was possible that Tom would come)
    •  I drew a map for Sarah in case she couldn't find the house.
    • We rang the bell again in case they hadn't heard it the first time.

    Put in case or if:
