The following is the definition of hypercorrection from Oxford Dictionary.
I don't understand the words which I highlighted in red. Could you rephrase it or explain it? I mean I understand each word, but I don't understand the phrase.The use of an erroneous word form or pronunciation based on a false analogy with a correct or prestigious form, such as the use of I instead of me as a grammatical object (as in he invited my husband and I to lunch).
What does a false analogy mean ? Why is it false?
The "analogy" in this example is the idea that "I" is always the proper choice. Lots of people say things like "Me and him went to the movies."
The correct English is "He and I" went to the movies.
Someone who has learned from this that saying "and I" is correct, has learned something false. He will extend that analogy to another instance in grammar. Making the analogy false.
Since he thinks "and I" is always the proper form, he will say "give the tickets to him and I." But it should be "him and me" in that use.
This person has constructed an analogy between the correct use of "and I" when it is a subject and the use of "and I" as an object.
That analogy is false.
