Ask the great god: can "estimate" and "probably" be used at the same time?

About is the abbreviation of about. It is an "estimate" of the state of things. It is a kind of cognition with uncertain results.

Estimation is also a kind of prediction that cannot accurately define the state of things.

It is roughly consistent with the connotation and extension of estimation.

In Chinese, although several nouns and adjectives with the same or similar meaning can be juxtaposed in a declarative sentence, judgment words with the same meaning generally cannot appear in a sentence at the same time.

This sounds awkward, too.
