Hi! I'm an english learner and I just wanted to know, well I've seen some people say for example:"I haven't though" like the used the word "though" at the end of some sentences and I don't know why and want to understand it. Thank you.
The usage is OK ('Some people have; I haven't though' = 'Some people have; but I haven't').
But it's also a common typo (='It's also a common typo though') - for 'I haven't thought'.
