The term innovation derives from the Latin innovatio, the noun of action from innovare. The word first came into modern use in 1540 and stems from the Latin innovatus, pp. of innovare "to renew or change," from in- "into" + novus "new".

Angelic acid isn't very angelic at all - it's a defence substance for certain beetles. It gets its name from the Swedish plant Garden Angelica (Archangelica officinalis) from whose roots it was first obtained in the 1840s. Its proper name is (Z)-2-methyl-2-butenoic acid. The other isomer (E) goes by the equally silly name of tiglic acid (from the plant Croton tiglium, the source of croton oil) and is also a beetle defence substance.
