There are loads of little phrases and metaphors which we use on a daily basis but which wouldn't be suitable for a fantasy world. Phrases like "flying under the radar" only make sense in a world where aviation and detection of planes etc are things that exist. Waiting "til the sun's over the yardarm" requires a culture in which naval technology involves square sails. Calling someone a "cheeky monkey" implies a culture that has had reasonably regular contact with small simians. And there are a lot of often more subtle phrases that you might not even realise would be anachronistic or out of place until you really stop to think about it - or even investigate the etymology of the phrase.
What phrases have you caught yourself using which would be anachronistic within your story, and how have you changed things to portray the same meaning without the anachronism? Have you ever read back and old story and found something you'd written which is anachronistic? Have you read a published book containing stuff like this?
