- -ful, as much as. Added to a noun to form an adjective meaning "as much that can fit into", "as big as …".
There are several Hungarian surnames (and eponymous street names) apparently with -nyi ending, however, they usually derive from the name of a settlement that ends in -ny, so they do not contain this suffix. Some examples are Öttevényi (from Öttevény), Herényi (from Herény), Ladányi (from Ladány), Petényi/Pethényi (from Petény). Hence, their derivation from the -nyi ending is unlikely, though possible (e.g. petényi “as big as an egg cell”, from pete “egg cell”).
