Lhammas
linguistic work by J. R. R. Tolkien

The Lhammas (/ˈɬɑ.mɑs/; Noldorin for 'Account of Tongues') is a work of fictional sociolinguistics, written by J. R. R. Tolkien in 1937, and published in the 1987 The Lost Road and Other Writings, volume five of The History of Middle-earth series.
Tolkien, a philologist, became fascinated by constructed languages, and invented stories to provide his languages with a suitable world, Middle-earth. This resulted in The Lord of the Rings and The Silmarillion. He peopled Middle-earth with Elves and other races, and in the Lhammas presented the theory that all Middle-earth's languages had a shared origin. In the document, he diagrammed the resulting "Tree of Tongues" and described the fictional history of the evolution of some 30 Elvish languages.
Scholars have noted the realism of Tolkien's family of Elvish languages, analogous to the Indo-European family, as well as his changing views of their linguistic history, which he shifted radically soon after creating the Lhammas. The result was that the Noldorin language described in the document and in the contemporaneous The Etymologies, soon became the Sindarin found in The Lord of the Rings, while the new Noldorin became just a dialect of Quenya; Tolkien redrew his "Tree of Tongues" accordingly.
Context
Tolkien's philology
From his schooldays, J. R. R. Tolkien was in his biographer John Garth's words "effusive about philology"; his schoolfriend Rob Gilson called him "quite a great authority on etymology". Tolkien was a professional philologist, a scholar of comparative and historical linguistics. He was especially familiar with Old English and related languages.

Why this record matters
“Lhammas” is worth following because a concise public description often conceals a longer documentary argument. Here, Lhammas, linguistic and work provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 6, 2026. The linked authority identifier is Q6538493. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1937 and 1987.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
