The term 'be-lied' is not common in English language usage, however, it is an inflected form of the verb 'lie' which means to make an untrue statement with intent to deceive. The antonym for 'be-lied' would then be 'believed' - which means to accept something as true, especially without adequate evidence. Other antonyms that can be used contextually include 'confirmed', 'affirmed', and 'endorsed'. These words all imply the presence of evidence or proof that substantiates a claim or fact, and as such can be used as antonyms for 'be-lied'. They convey a sense of trust and assurance in the truthfulness of a statement or assertion.
