This drives me mad! But I see it in posts that are otherwise completely literate and often wonderfully eloquent. I wondered if it might be a typo of predictive text, but surely then you'd see 'bought' for 'brought' occasionally, or 'though'/' thought'/'through' mixed up sometimes.
I don't know if people make the error verbally because I don't hear well enough to pick up the difference (either that or no one I speak to makes the mistake!).
It's becoming increasingly common to read and I really have to fight the urge to correct the poster.
What do you think? Do these people actually think the word is' brought' or is it down to predictive text?
