I've used half rhymes before in other writings.
One would assume that "plus" would rhyme better with "fuss," but are taken off guard when they see "minus" because they never heard of half rhymes before.
All you have to do is pronounce it a few times in your head or vocally out loud:
Full rhyme (with "plus") -
A decent job, / even with all the fuss.
fuh'ss.
I hereby score you, / a solid B plus.
pluh'ss.
Half rhyme (with "minus") -
A decent job, / even with all the fuss.
fuh'ss.
I hereby score you, / a solid B minus.
nuh'ss.
Another example from
one of my writings:
Words cannot speak, but my heart silently
move my lips to the flow of time's passed by
To where we once begun and ne'er see
what had clouded our hearts that ne'er lie.
The words "silently" and "see" are half rhymes. They rhyme on "-ly" (lee) and "see" (see). The stanzas, or quatrains, follow the form of abab as you can see above.
Since writing is a hobby of mine, reading whatever Shantotto says in the game makes me feel pretty elated just to see them. There are, surprisingly, creative writers for this game. (Well, US version since I believe she doesn't rhyme in the Japanese version if I recall correctly).
I'm actually looking forward to the next and last mini-expansion because of her. It would be like reading one long rhyming poetry in every cutscene from beginning to end, as if you were reading the sonnets of a Shakespearean play. (Though, of course, not in the same quality.)
