In the last chapter of A Canticle for Leibowitz, a priest makes a pun:
“Onerem accipisne?” [Do you accept the burden?]
“Honorem accipio.” [I accept the honor.]
In classical Latin, onus ‘burden’ is neuter, so the accusative is onus not onerem. Even a dead language, it seems, changes at least a little bit during the future dark ages.
April 20: Oops, I misremembered. The first priest’s line is tibine imponemus oneri? [Shall we impose the burden on thee?] — where ‘burden’ is instrumental, not accusative.
