Lubicie, pamiętacie, mówicie

Hello, I need some help understanding the following words in context. Lubicie, pamiętacie, and mówicie. They both
are present/past tenses. But what are some examples? Am I directing toward a group of people?

Lubicie - you like ( plural) Lubiliście- you liked (plural)

Pamiętacie- you remember (plural) Pamiętaliście- you remembered ( plural)

Mówicie- you say (plural) Mówiliście- you said (plural)

You answered your own question it seems. I don't know a lot of Polish, but the -cie conjugation is used for, as you said, addressing groups of people. At least that's how I'd use it

"Lubię czytać" - I like to swim
"Czy lubisz czytać?" - Do you like to swim? (one person, direct, informal)
"Czy pani lubi czytać?" - Do you like to swim? (one person, female, direct and formal)
"Czy lubicie czytać?" - "Do you like to swim? (addressed to a group of people)

Maybe someone will correct me though :)

well, it is the second person PLURAL, so yes, you would be addressing at least two people ...

czytać - to swim

that's a new one...

Yeah I originally wrote 'Pływać' and decided to change it to one of the first verbs you learn, but forgot to change the description to read :P
