Hey Márcio -

Many English noums can generate an adjective by adding "ful" like zest->zestful.

Many English adjectives can generate a noum by adding "ness" like good->goodness.

Combine the two concepts gets you a noum like "shame" going to adjective "shameful" then back to a noum "shamefulness".   The final noum sometimes means the same as the original noum, but not always.

Go to http://www.onelook.com/ and enter " *fulness " to get a list of over 200 words that end in "fulness",  from abusefulness to zestfulness.

Happy word games.
