From in- (“not”) +‎ nocuus (“harmful”).

• (Classical Latin) IPA^(key): [ɪnˈnɔ.ku.ʊs]
• (modern Italianate Ecclesiastical) IPA^(key): [inˈnɔː.ku.us]

innocuus (feminine innocua, neuter innocuum); first/second-declension adjective

1. harmless, innocuous
2. blameless, innocent, guiltless
   • 8 CE, Ovid, Fasti 2.623:

     innocuī veniant.

     Let [those people who are] guiltless come [forth].
     (The ancient Roman festival Caristia united family members and encouraged reconciliation of their differences. Ovid, however, here writing satirically, uses the present active subjunctive verb veniant to invite only guilt-free relatives to gather. In the following verses, the poet tells the troublemakers to stay home! And Ovid's sly intent can be playfully translated with other meanings for innocuus listed here.)

3. unharmed, unhurt, uninjured

First/second-declension adjective.
