[tex-hyphen] Dictio-nary ?

[Doug McKenna]

I just noticed that TeX (2021) is placing a hyphen before the 'n' in "dictionary" rather than after.  Two dictionaries I've self-referentially looked at both say that the second syllable of "dictionary" is "tion", as in "dic-tion-ar-y".

Here's a MWE, using the TUGboat class for a narrow column:

%%%%%%%%%%%%%%
\documentclass{ltugboat}
\begin{document}
Dictionary, and dictionary, dictionary, dictionary.
\end{document}
%%%%%%%%%%%%%%

Is this a hyphe-
nation bug requiring an official exception?
