Scottish poetry means the words that Scottish people use to talk about their feelings and the world around them, but make them sound pretty and rhyme. Modern Scottish poetry means the poems that have been written more recently by Scottish people that still use pretty words, but they might talk about different things or use different styles than older Scottish poetry.
Faber is a company that helps print and publish books, including books of poetry. They have chosen to gather and share some of the modern Scottish poetry that they think is really good, so other people can read it too. This collection might include poems about nature, love, or Scottish history, and they might be written by men, women, or people of different backgrounds. By putting these poems in a book, Faber is making it possible for people all over the world to read, enjoy, and learn from Scottish poetry.
