Generalarization of uncountable nouns is possible?

Is generalization of uncountable nouns possible?
I think it is partly 'yes'.

(1)Nouns that end with '-ity' tend to be uncountable.
eg. utility, productivity

(2)Nouns that end with '-ism'' tend to be uncountable.
eg.globalism, agism

(3)Nouns that end with '-tion' tend to be uncountable,
but there are many exceptions.
eg.confusion, corruption

(4)Nouns that end with '-ization' tend to be uncountable,
but I'm not sure if this is correct.
eg. globalization, democratization

Are the above rules correct?
Is there any other rule about uncountable nouns? ;-)
Thank you.

These are generalisations, so they do have exceptions- 'utilities' exists, meaning electricity and water comapnies, and 'witticism' is countable. You could add -ology to the list. ;-)

Thank you for your reply, tdol.
'-logy' also tends to be uncountable, OK.

By the way, does any semantic category have a tendency to be uncountable?

According to my observation, environmental terms tend to be uncountable such as 'global warming', 'environmental destruction', 'air pollution' and 'desertification'
. Is there any other semantic category that tends to be uncountable?

:-)

The words that are derived from Latin and Greek tend to be more technical, so they cover more subjects, concepts, etc, which is why many are uncountable. ;-)
