'mundanely-executed' originates from the combination of 'mundane' and 'executed'. 'Mundane' comes from Latin 'mundanus', meaning 'worldly', and 'executed' from Latin 'executus', meaning 'carried out'.

'mundane' changed from the Latin word 'mundanus' and 'executed' from 'executus', eventually forming the modern English compound 'mundanely-executed'.

Initially, 'mundane' meant 'worldly' and 'executed' meant 'carried out'. Together, they evolved to describe something done in an ordinary manner.
