Word for repetition of the same word before and after comma?

How do you describe a type of writing in which a word is repeated (e.g. a word written before as well as after a comma), such as:

• "My point is that we cannot, cannot believe in a loving, forgiving, merciful, compassionate God that is exclusive." —Quora Source

• "He just made the minimum height to ride the roller coaster and he's just an awesome, awesome boy." —Example sentence suggested by @1006a.

• "His speech is quite, quite fabulous"

One of my coleagues suggested the term anaphora which denotes:

1. the use of a word referring back to a word used earlier in a text or conversation, to avoid repetition, for example the pronouns he, she, it, and they and the verb do in I like it and so do they.

2. the repetition of a word or phrase at the beginning of successive clauses.

3. the part of the Eucharist which contains the consecration, anamnesis, and communion.

I think it's not a word which I am looking for because it refers to the repetition of a word or phrase from the starting of a sentence. See the following example of anaphora:

Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to make justice a reality for all of God’s children.

Solution 1:

The technical term is epizeuxis:

In rhetoric, an epizeuxis is the repetition of a word or phrase in immediate succession, typically within the same sentence, for vehemence or emphasis.

but I must admit I had to look it up. According to LitCharts, it comes from an ancient Greek word meaning "fasten together."

Solution 2:

Palilogia or palilogy/palillogy (synonymous to epizeuxis) also describe this type of repetition in rhetoric.
