Prandial

Prandial (pronounced pran-dee-uhl)

Of or relating to a meal, especially dinner (sometimes affected, jocose or facetious).

1810-1820: From the Late Latin prandialis or the Classical Latin prandium (late breakfast; lunch), perhaps from the primitive Indo-European pr̥hemós (first), from prehe- + -edere (to eat) + the Latin -ium (the suffix forming nouns), ultimately from the primitive Indo-European -yós (suffix forming adjectives from noun stems) +‎ -al (the suffix forming adjectives).  The primitive Indo-European ed- root (to eat) meant originally "to bite".  It’s never been clear why the meaning shift from the Classical Latin meaning (late breakfast; lunch) to the later (dinner) happened.  Now, prandial is used almost exclusively as (a usually jocular or affected) pre-prandial or post-prandial (often plural), a reference to before or after-dinner drinks.  The adverb is prandially.

The first use of the adjective postprandial (now usually as post-prandial) seems to have been by the poet Samuel Taylor Coleridge (1772–1834) in 1820 to convey the meaning "happening, said, done etc; after dinner".  The first known instance of preprandial (also pre-prandial) (before dinner) is in a letter of 1822 by the poet Charles Lamb (1775–1834) to Coleridge: “Why you should refuse twenty guineas per sheet for Blackwood’s or any other magazine passes my poor comprehension. But, as Strap says, you know best.  I have no quarrel with you about præprandial avocations—so don’t imagine one.”
