As promised in a past previous post, a quick breakdown of Tautology and it's proper usage.
Tautology seems to get used on the board as some sort of antonym of irony, which is not. It's listed as a synonym for repetitiveness, but that lacks proper context. For example, Trump was not being tautological when he claimed thousands of times that the election was going to be or was stolen, but he was definitely repetitive.
Tautology would be better thought of as synonymous to verbose or wordy (see my posts). Tautology is using words/phrases that have same/similar meaning when it's not necessary - a stylistic error. For example, in a past previous post.... The easy way to identify tautology vs repetitiveness is base it on need. I could have said in a past post or in a previous post and the meaning isn't altered, so I'm using an unnecessary word.
OTOH, when Trump repeats over and over that the election was stolen, it's politically necessary. He's pounding his message home over and over and over again. Another example, of repetitiveness vs tautology would be how I just used "over and over and over again" which is not a tautology, but a stylistic choice (not a stylistic fault) to demonstrate how repetitive Trump's message has been. Trump's repetition serves a purpose: he's staying on message, delegitimizing Biden's presidency, it's a way to measure loyalty to Trump, etc. If Trump were to stop repeating the "Big Lie," people would wonder if he's moved on, how would I differentiate from a McConnell republican vs a Trump republican, etc.
So in conclusion, when one is repetitive, they are not necessarily being tautologic.
