can you please explain the difference in use between even if and even though
"even if" is used when a) we are talking about something that hasn't happened yet and b) when we don't know if something happened or not.
a) Even if it rains, they will go hiking.
b) Even if it rained, they will have gone hiking.
"even though" is more complicated. It is usually used when something has already happened.
Even though it rained, they went hiking.
But "even though" can also be used in situations in which "even if" is usually used.
Even though it may have rained, they will have gone hiking. This is another and longer way of expressing b) above.
Although "even if" and "even though" begin all the above sentences, the two phrases can appear later in those sentences.
The above is a start and maybe someone else will add something. Feel free to ask further questions.
'even if' means despite the possibility that...something might happen or eventuate or be the case
'even though' means despite the fact that...it was the case/did happen
So: Even if it rains, the concert in the park will still go ahead.
Even though it rained, the concert in the park went ahead as planned.
The confusion arises in sentences with more similar meanings:
Even though he has few friends, he does not feel lonely. - a fact: he has few friends
Someone says that another person doesn't seem to know many people in the community, have many friends.
Another person replies:
Even if he does have few friends, he still seems a happy person. - The sentence says, 'that is possible, but he still seems happy'
