\hyphenation ¶Synopsis:
\hyphenation{word1 ...}
Declares allowed hyphenation points within the words in the list. The
words in that list are separated by spaces. Show permitted points for
hyphenation with an ASCII dash character, -.
Here is an example:
\hyphenation{hat-er il-lit-e-ra-ti tru-th-i-ness}
Use lowercase letters. TeX will only hyphenate if the word matches
exactly; no inflections are tried. Multiple \hyphenation
commands accumulate.
