I'm thinking of things like 'hacks'.
To hack used to only mean (in slang) to be able to do something. 'Can you hack it?'
Now we have 'life hacks' and all kinds of 'hacks'.
'To learn' has been corrupted into 'learnings'.
I also hate the expression 'go to' when it means something you choose above anything else. Like the 'Packed lunches - your go-tos' now trending here.
Ok hands up, I'm a writer so language matters to me, but more and more I'm made to think 'What the hell is that supposed to mean?'
