Tautegorical is a term frequently used in philosophical debates to describe an absolute or categorical statement. In the realm of synonyms, several words can be substituted to convey a similar meaning. "Categorical" is arguably the most common synonym, as it captures the unequivocal nature of an assertion. "Tautological" is also frequently used, referring to a statement that is repetitive or needlessly redundant. Another option is "dogmatic", which emphasizes the stubbornness and unwavering certainty of a proposition. Lastly, "absolute" can be employed to convey the idea of a definitive, uncontestable statement. These synonyms effectively convey the incontestable or unwavering nature of a tautegorical claim.
