Have you ever got the wrong word stuck in your head?

At work I have been referring to a Doctors specialty as their speciality.

My colleague was finding this so frustrating that he provided me with a tool to help.

This ‘special tea’ is perched on my monitor, and is helping to remind me of the word I need.

Sometimes repetition helps, especially when you are trying to train your brain.

What words do you get muddled up?
