(C) hypercorrections
(D) lexical diffusions

(A) A grapheme (from the Greek: γράφω, gráphō, "write") is a fundamental unit in a written language.  For example, the word ship contains four graphemes (s, h, i, and p) but only three phonemes, for sh is a digraph

(B)Euphemism is a substitution for an expression that may offend or suggest something unpleasant to the receiver, using instead an agreeable or less offensive expression,^[1] or to make it less troublesome for the speaker.

(C)A pronunciation, word form, or grammatical construction produced by mistaken analogy with standard usage out of a desire to be correct. Perhaps the most common example of hypercorrectness is the use of I for me in a compound subject: between you and I.

The phenomenon is that by which a phoneme is modified in a subset of the lexicon, and spreads gradually to other lexical items. For example, in English, /uː/ has changed to /ʊ/ in good and hood but not in food; some dialects have it in hoof and roof but others do not;
