Spending a few minutes on Italian grammar will help you avoid confusion and make everything much easier, we promise.
Here are the Italian grammar rules for plurals:
If a word is masculine, the article changes and the ending goes from -o to -i:
il pomodoro, i pomodori
If a word is feminine, the ending changes from -a to -e
la tiella, le tielle
If a masculine word begins with z, or an s followed by a consonant (the 'impure s'), it takes the article lo (plural gli, pronounced 'lyee').
lo stinco, gli stinchi
Italians are precise about singulars and plurals; it's just the way the language works. We anglophones couldn't imagine saying 'uno spaghetto', for just one strand of spaghetti.
