Rare and mostly used in poetry. Note that the more common indecōrus cannot be used in dactylic meters because it contains a long-short-long syllable sequence. Servius the grammarian, observing that most masculine nouns ending in -or form a genitive singular in -ōris (with long -ō-), supposes that this word might lack a nominative singular. As an alternative to this, some dictionaries hypothesize a two-termination nominative singular, indecoris/indecore.

Third-declension one-termination adjective (non-i-stem).
