We can use 'even' in comparisons to say that the comparison is surprising or to make comparison stronger.

• He’s even more polite than his brother (= his brother is really polite, so he must be really, really polite.)

• Sarah is even richer than George. (= George is very rich, so I find it surprising that Sarah can be richer than him.)

'Even though' is used to make ‘though’ stronger. It means ‘despite the fact that’.

'Even if' is also used to make conditionals stronger or to say that the conditional is surprising.

'Even so' also tells us about something that is surprising. It’s used in the same was as ‘despite what I just said’. It needs to go in the middle of two pieces of information.

• It was really hot. Even so, we were walking around the city all day. (= despite the fact that it was hot, we were walking around the city all day.)

• I was wide

awake until 4am but even so I managed to get up at 7am.
