Adjective

?soscel?s (genitive ?soscelis); third-declension one-termination adjective

1. (geometry) isosceles (having equal legs)

Declension

Third-declension one-termination adjective (Greek-type).

¹It is unknown if Classical Latin preserved (or would have preserved) the shortness of the original Greek short ending.Notes:

• The Greek masculine and feminine nominative singular is ????????? (isoskel?s), while the masculine and feminine vocative singular and the neuter nominative, accusative and vocative singular are ????????? (isoskelés). Maybe Latin preserved the short length of the epsilon (?), or maybe it did not so that the declension became similar to Latin third declension adjectives of one ending (like felix).
• This word is often used together with triangulum n and rarer with triangulus m.
