Sindarin Plurals and I-Affection
Most familiar English plurals add a visible ending. Sindarin ordinary plurals frequently change vowels inside the noun instead, reflecting the historical influence of a lost plural i.
The central pattern: i-affection
The ancient plural marker affected vowels in the preceding word before the ending itself disappeared. The surviving vowel changes are therefore the plural signal. This resembles English man and men, except that internal change is the normal Sindarin strategy rather than an isolated irregularity.
The result depends on syllable position, vowel length, nearby consonants, and the history of the word. A short replacement table is useful for orientation but cannot derive every plural correctly.
Familiar examples
| Singular | Plural | Meaning |
|---|---|---|
| adan | edain | man / men |
| aran | erain | king / kings |
| orch | yrch | orc / orcs |
| amon | emyn | hill / hills |
| êl | elin | star / stars |
| naug | noeg | dwarf / dwarves |
The plural article adds another layer
The plural definite article is historically in. Before some consonants its n is chiefly visible through nasal mutation of the following word, while before vowels the full form can remain clear. A plural noun phrase may therefore combine internal vowel change with a changed initial consonant.
This interaction is why pluralization and mutation cannot always be treated as independent search-and-replace operations.
Ordinary plurals and class plurals are different
The suffix -ath can form a collective or class plural: it refers to a people, host, or complete kind rather than simply counting several individual nouns. Periannath, for example, is a collective name for the Hobbit people, not merely a mechanical plural of one Hobbit.
Lamethir’s productive beta rule focuses on ordinary plurals. Direct dictionary entries take priority, and reverse analysis verifies a proposed singular by reapplying the forward plural rule.
