-alis

• -āris
• -ēlis
• -īlis
• -ūlis

From Proto-Indo-European *-li-, which later dissimilated into an early version of -aris. Perhaps connected to *h₂el- (“to grow”) (cf. the sense of indolēs, from this root).

• (Classical) IPA^(key): /ˈaː.lis/, [ˈaː.lɪs]
• (Ecclesiastical) IPA^(key): /ˈa.lis/, [ˈaː.lis]

-ālis m or f (neuter -āle); third declension

1. Used to form adjectives of relationship from nouns or numerals.

The suffix -ālis is added to a noun or numeral to form an adjective of relationship to that noun.

Examples:

‎duo (“two”) + ‎-alis → ‎duālis (“that contains two”)

‎nātūra (“nature”) + ‎-alis → ‎nātūrālis (“natural”)

‎rēx (“king, ruler”) + ‎-alis → ‎rēgālis (“regal, royal”)

If the root word ends in -l or -lis, -āris is generally used instead. Sometimes both forms are found; e.g., līneālis and līneāris.

Third declension.
