"a wottle of bine", "a can of boot reer" and "holed and sealed" - What types of speech errors are these?
Solution 1:
I think you are referring to spoonerism : (from Wikipedia)
- is an error in speech or deliberate play on words in which corresponding consonants, vowels, or morphemes are switched between two words in a phrase.
A similar error is metathesis:
the re-arranging of sounds or syllables in a word, or of words in a sentence. Most commonly it refers to the switching of two or more contiguous sounds, known as adjacent metathesis or local metathesis:
foliage > foilage
cavalry > calvary
