Hi
I am always not quite sure about normal use in plural of such (abstract) nouns. (Albeit I know that paradoxes is correct).
Can you say (for example) which headings sounds to you better:
Life is full of paradoxes
or just
Life is paradoxical.
Hi Tamara
I have no problem with paradoxes whatsoever. 
Amy
Thank you, Amy.
(Does it mean that your life is so full of paradoxes that you got used to having them
in plu… in plenty?.. 
)
Hi Tamara
Ha ha. 
The paradoxes in my life are countable (not quite innumerable ;)) but I haven’t necessarily gotten used to them all. :lol:

Amy, the true reason for my question was that at least two natives, when asked, didn’t know whether the plural form for the noun exists.
And I had to check dictionaries.
Hi Tamara
Actually, that’s not so unusual. I’ve often found it to be the case that when you ask a native speaker a very specific question about language, they’re sometimes unable to answer. You’re requiring thought and analysis when you pose such a question. :shock: And the language of a native speaker is done unthinkingly — mainly “feeling”.
