The most used definition of a Spoonerism is 'I hissed a mystery lesson'. Transposition of start letters, but 'y' is used instead of 'i' when written. Hope it helps.
Spoonerisms are usually transpositions of the initial consonant sounds, but sometimes it can be vowels, as in:
it is kistomary to cuss the bride
(See metathesis)
It's quite frustrating for those who haven't done the crossword to follow how this works. Obviously lentil is correct from above but why? Are the unclued answers vegetables or what? What is 13 across relevance? Finally I'd say lentil for lintel is not a spoonerism, malapropism maybe.
Hi Prudie
I haven't see the crossword, either
Most Spoonerisms are apocryphal. Apparently the only one the Rev Spooner acknowledged was in the words of a hymn, when he said
Cinquering Kongs for Conquering Kings - a vowel transposition, as in lintel and lentil...
Yes, quite so, although Spoonerisms traditionally include two words I see no reason it cannot occur within a single word itself and the fact it's also an anagram is irrelevant really.
You know clearly it's lentil and have no interest in disagreeing but for the uninitiated every definition of a spoonerism online is along the lines of "a transposition of usually initial sounds of two or more words (as in tons of soil for sons of toil)"
