What was the name of the literary group J.R.R. Tolkien attended with C.S. Lewis?

The literary group J.R.R. Tolkien attended with C.S. Lewis was called the Inklings.

The Inklings were an informal Oxford literary discussion group that met mainly during the 1930s and 1940s. Tolkien and C.S. Lewis were prominent members, and meetings often involved reading works in progress aloud and discussing literature, theology, and writing.

The group was not a formal society with a fixed membership list or a published manifesto. Its name came from the idea of an “inkling,” meaning a hint or suggestion, and it suited the group’s informal character.

Tolkien read portions of The Lord of the Rings to fellow Inklings during its long composition. Lewis’s encouragement was important to Tolkien, although the two friends also disagreed about style, religion, and aspects of each other’s fiction.
