Linguistic Codex: Agglutinative Roots & Suffix Stacking

The Eldarin languages are structurally **agglutinative**. They build compound words and inflectional inflections by stacking unambiguous, monosemantic prefixes and suffixes onto a central, monosyllabic etymological root. For instance, from the root √MEL "love", the addition of adjectival -ā gives mela "dear", which with the noun-agent suffix -indo becomes melindo "lover (m.)", and with the plural inflection -r yields melindor "lovers".

The **Radial Sunburst Diagram** on the left dynamically graphs this evolutionary tree of etymological derivations for any productive root. The core circle is the selected ancestral root. Concentric layers explode outward: Level 1 shows immediate derivations, and Level 2 displays compounds and tertiary derivations. Arcs are color-coded by dialect: golden-amber arcs signify **Quenya** developments, while forest-green arcs represent **Sindarin** innovations. The **Grammatical Decay curves** on the right show how words categorized as pure root concepts gradually evolved into structured parts of speech (nouns, verbs, adjectives) as Eldarin moved from the Primitive Era down into Classical Third Age historical epochs.
