idiolect (ID-ee-uh-lekt) noun

Language usage pattern unique to a person.

When I first saw this word, I could not think of a way to make a post about it. But just now I remembered that our peerless poster, faldage, has one word he uses to self-deprecatingly avoid linguaphile ostentation: "parbly."
It suddenly seemed to me that this is an idiolect of his, since he alone uses it. But what to say about it?
Finally it dawned on me that it might be described by some of the rhetoric terms which I have trouble remembering for more than five minutes. Since his word is presumably an alteration of the word "probably", it has undergone two forms of metaplasm: antisthecon, and syneresis
Antisthecon is the substitution of a sound, syllable, or letter within a word.
Syneresis is the contraction of two syllables into one.

Are there others that I missed?.
