Poetry is a wonderful way to learn a language, and some poems are better suited than others for that purpose. The Owl and the Pussycat is one of my favourite poems, and it is a particularly fine poem for English language students.
Her Brittanic Majesty is Queen Elizabeth II. The II (two) is her regnal number, and the entire monicker, Elizabeth II, is her regnal name. All monarchs choose a regnal name upon ascension to their throne.
