Word of the week: sesquipedalian

I am currently reading Attention all shipping: A Journey Round the Shipping Forecast by Charlie Connelly, and stumbled upon this intriguing word on page 4. As a young teenager keen to make my mark in a tough rural girls grammar school I had a 'word of the week' for a short while. Perhaps if I had maintained this strict regime I would have now known the meaning of sesquipedalian and not had to interrupt my reading in order to blog about it.
