So, what is the difference between the terms? Is it right to say that elision is a specific case of contraction? Another version I’ve I ran onto was that these were slightly different terms as contraction always refers to the case when there’s more than one word.
An elision refers specifically to the removal of sounds from speech, while a contraction refers to a shortened version of writing words, that can represent that spoken elision in English. A contraction though is not always a written representation of that elision because a contraction can represent other things as well.
Additionally, an elision is NOT always turned into a contraction in writing, though.
