Is there any simple chart for making a noun plural? My Google searches come up with lists and examples but no clear rules or sets of examples that demonstrate clear rules like masculine nouns being pluralized with -y and feminine with -i or something so obvious. It seems quite random from the poor examples I have seen. The plural lesson here on Duolingo has no descriptions or explanations like some lessons do.
Does it follow a pattern like the (-y -a -e) male/female/neuter pattern for adjectives or the similar patterns for declining noun cases? I need some sort of consistent structure to try and memorize or else I am guessing every time with plurals.
Page 16 of "Polish Grammar in a Nutshell" has a chart of plural noun declensions, and there is also a printer friendly chart of noun declensions here: http://www.polish-translators.com/deklinacja.html
