I read a grammar book a few years ago and remember coming accross a term for switching the first two letters in a word. I cannot for the life of me remember what the term is.
An example would be the name "Leo" being pronounced as "Elo".
I cannot remember if it was specifically involving the letter 'l', but I do know that it is not a spoonerism.
I do not remember it being classified as an impediment, more of a mispronunciation in early speech development since it is common in toddlers' speech.
Any help would be greatly appreciated — it is really bugging me now.
