I try to gently correct Josh and Aves when they say things incorrectly (e.g. writed), but I quite enjoy the learning process that comes with discovering new words and explaining why words are pronounced the way they are.
Recently, I noticed that my strictness is somewhat selective. A good example is the word versus. Josh has turned it into a verb and uses it to say things like 'Today, the red team was versing the blue team.'. I corrected him once, but then I realized that I smiled each time he said it because it is an interesting derivation from the word versus. I find that I don't correct him anymore when he says it.
The other day, I heard him say the word oftenly. ("I do it oftenly because...blah, blah, blah.") Again, I found that I didn't want to correct him. I liked the word! Ha.
So, even though I will continue to cringe when I hear the word 'orientated' instead of 'oriented' (yes, I know it's acceptable!) and 'real' instead of 'really' and 'I says' instead of 'I said', apparently, I'm ok if I hear 'versing' and 'oftenly'. Now, if he is 18 and still saying either, I wonder if I will be still be ok with it...
