常常 expresses frequent repetition of an action.
In a sentence, it should come before a predicate or before anт adverbial modifier of time.

他常常去跑步
He often goes running
tā chángcháng qù pǎobù

Pay attention
We also cannot use 常常 in negation or with adverbs of degree. For example, it’s incorrect to say 不常常 or 很常常.
The adverb 常
This adverb 常 is used less frequently than 常常.
In a sentence it should come before a predicate which is expressed by a verb. For example:

We can put another adverb of degree before 常. For example, 很 .

他很常说我是个好人
He often says that I’m a good person

她常看的那本书是《战争和和平》
The book she always reads is “War and Peace”
tā cháng kàn de nà běn shū shì “zhànzhēng hé hépíng”
We also can use 常 with the negative particle 不 . In which case it means “not often”.
