Pedantry!

I fucking hate it when people (especially coppers) talk about /greev-y-ous/ bodily harm:

Grievous - /greev-ous/

And the old chestnut of people talking about how someone was 'disinterested' when they mean 'uninterested' (disinterested means 'unbiased').

Not sure I've seen these examples on the forum, but I do feel better now.

Listen out for 'burglery' rather than 'burglary'. You hear the former much more frequently than the latter.
