From Proto-Indo-European *-li-, which later dissimilated into an early version of -āris. Perhaps connected to *h₂el- (“to grow”) (cf. the sense of indolēs, from this root).
-ālis (neuter -āle); third-declension two-termination suffix
- Used to form adjectives of relationship from nouns or numerals.
The suffix -ālis is added (usually, but not exclusively) to a noun or numeral to form an adjective of relationship to that noun.
- anima (“life”) + -ālis → animālis (“living”)
- duo (“two”) + -ālis → duālis (“that contains two”)
- nātūra (“nature”) + -ālis → nātūrālis (“natural”)
- rēx (“king, ruler”) + -ālis → 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 two-termination adjective.
