"hood" denoting a condition or quality when we use it as a suffix. For example, falsehood, neighborhood. But we don't say "truehood", "brotherhood". I'm wondering in what condition we can use "hood" as a suffix.
It is rare in English that two words with the same root word will have identical meanings; if they come into being they tend to gain different nuances. I think a 'truehood' would mean exactly the same as 'truth', so it's never been needed.
