I already know English language does not allow hyphenation of one-syllable words, that is why I am not asking this question on english.sx.
But I am facing a typesetting task (humanities) with a very small layout which cannot be changed, and with a font and font size that cannot be changed, too.
I have some occurences where one-syllable words, such as thought, overflow the margin, see second instance here:
I am already using microtype, which helps a little, but not enough.
My question is if it is typographically acceptable to force hyphenation in one-syllable words in rare circumstances?
Could I have that example as thou-ght?
It is wrong, but will it be tolerated by an English readership?
If not, what can be done to accomodate such a situation? What would a professional typesetter do?
