We do not typically use a comma before or after an adverb of degree in a sentence.

- when adding nonessential information,
- when using sentence adverbs, or
- after an introductory phrase.
1. Quick Review of Adverbs of Degree
Adverbs of degree help us describe "how much" or "to what degree" we do something. They can also specify the degree to which an adjective or another adverb applies.

1.1 Types of adverbs of degree
Some adverbs of degree can be used as amplifiers (e.g., extremely, absolutely, strongly, completely, heartily, very, really, totally, too, seriously, badly, greatly).
The soup is extremely hot.
That event entirely changed my life.
Other adverbs of degree are down-toners (e.g., mildly, sort of, kind of, fairly, almost, to some extent, rather, quite, nearly, enough).
The flavor is mildly sweet.
She is fairly quiet.
Adverbs of degree are commonly placed before the verb, adjective, or adverb they describe.

When using an auxiliary verb, the adverb of degree usually goes before the main verb.
He has almost finished.

The adverb "enough" always goes after the adjective or adverb it modifies.

By contrast, as a determiner, "enough" goes in front of the noun it determines.

The adverbs "very" and "too" (when meaning "excessively") go before the adjective or adverb they describe.

2. When to Use Commas With Adverbs of Degree
2.1 Adverbs of degree in mid-sentence
When an adverb of degree is used in mid-sentence to modify a single word (verb, adjective, or adverb), we do not use a comma to separate the adverb from the word it modifies.
He is extremely arrogant.
He is extremely, arrogant.
But there is an exception to the practice of not placing a comma between an adverb and the word it describes. When repeating an adverb of degree for emphasis, we use a comma to separate both instances of the same adverb.
She is a very, very cute girl.
An adverb of degree may also be preceded or followed by a comma when adding a parenthetic expression or an interrupter of the sentence flow.

Place a comma after the adverb (or the adverb phrase) of degree if it reflects the writer's view or opinion rather than describe a single word. In such a situation, the comma signals that the adverb applies to the sentence as a whole.
