Welsh rarebitWelsh rare·bit
Some insist that it be pronounced identically to rabbit, as the spelling is a corruption, while others insist that it be pronounced as rare-bit specifically to differentiate it from actual rabbit meat.
Some object to the use of the term “Welsh rarebit" as a foolish error, and prefer Welsh rabbit.
Corruption of Welsh rabbit.
First attested by Francis Grose in A Classical Dictionary of the Vulgar Tongue in 1785; he erroneously marked Welsh rabbit as a corruption (inverting the historical order); this idea may have originated with him, or been widespread at the time.
