Yes, panini is just the plural form of "panino", meaning sandwich

Ciao, Sharon. Yes, "panini" is the plural of "panino". Since panino ends with an "o", following the general rule, the plural will end in "i". A presto, Gloria

Hi, no need for surprise: maybe if you normally read "Pizza" (singular) you would expect that, if a shop makes sandwiches, they should write "Panino" (singular), but there's no really rules for that as it really depends from the article: -- sometimes it's better to use an uncountable/collective form which is the most used ("cartoleria", "gioielleria", "ferramenta" etc); -- or a plural form ("articoli per la casa", "gioielli"); -- or a singular one which however is a bit rare ("pizza", "vendo-oro", "pesce fresco"). Obviously the plural form is rather natural when it deals on a shop. bye
