Pravda means truth. Pravda was also name of state journal. The half-truth is said as half-pravda. English has many words for lie too: misinformation, lie, untruth, false, deceit, deception, dishonesty, disinformation, distortion, evasion, fabrication, falsehood, fiction, forgery, misrepresentation, perjury, slander, tale. I got them from synonyms dictionary.

That does not say anything about English speaking people other then their language is rich and can express nuance.
