Linguistic Codex: Root Derivations & Productivity

In Tolkien's Eldarin languages, vocabulary expands organically through affix-stacking and compounding from basic monosyllabic roots. Roots are traditionally capitalized in modern lexicons (e.g. √CAR "do, make", √GALAD "shine", √MEL "love"). The size of root nodes in this visualization corresponds to their morphological productivity (the number of direct and indirect derived words). Filter by Language Era to see how these networks split, or search for a specific word to load its ancestral lineage.
