What is the name for the transformation of "good on you" to "onya"?
In Australian slang, there is a word "Onya" which is used in the exact same way as "Good on you".
What transformations have taken place in the formation of this slang? I'm finding it difficult to see since "Good on you" is not a single word. I think there is vowel reduction "you" -> "ya" (schwa phoneme). But what else is there, elision, shortening?
Solution 1:
The grammatical dropping of complete words from a phrase is known as:
ellipsis.
Sometimes the plainer term 'deletion' is used.
(Elision and syncope and apocope and etc are used for phonological dropping of sounds).
