Here is an example:
Please do not obfuscate the truth.

He attempted to obfuscate the truth by providing vague and misleading information during the investigation.

Obfuscate is when you purposely obscure, hinder or make something hard to understand. It is also when you attempt to bewilder.

muddy, obfuscate

A 'sentence' can mean two things:

1. A discrete collection of words or utterances relating to the same subject.

2. A legal punishment.

Since I know of no standard legal sentence containing the word 'obfuscate', I assume your question relates to the former definition. Therefore, the answer would be: 'A discrete collection of words relating to the word 'obfuscate'.'

Hope that helps.
