Meaning of the word ' itular' [closed]

While looking up synonyms of the word 'so-called', I stumbled upon 'itular', of which I've never heard, and for which I can't seem to find additional (digital) sources. The dictionary itself gives a misspelling.

My first hunch was that it's a misspelling of 'titular', but, based on the synonyms, they seem to have different definitions.

Does anyone recognize the word, or can anyone provide a definition and/or an etymology of the word?

By analogy with table/tabular, title/titular, and so on, "itular" should mean "having the properties of an itle". But since there is no such thing as an "itle", "itular" doesn't mean anything.
