The title of J.R.R. Tolkien’s poem collection The Adventures of Tom Bombadil is written in English.
The collection was published in 1962 and contains sixteen poems. Only two directly concern Tom Bombadil; the others present songs, legends, and verse associated with the peoples and places of Middle-earth. Tolkien framed the poems as material from the Red Book tradition rather than as a straightforward modern anthology.
The book’s poems use several styles, including comic verse, narrative ballads, and imitations of traditional English forms. This makes it different from The Silmarillion, which primarily presents mythic prose and genealogical history.
Tolkien did invent and use languages such as Quenya and Sindarin, but the collection’s title and poems are presented in English. Some poems include invented names and references from his legendarium, which can make readers mistake the language of composition for one of his fictional languages.
