Tacky? Or a good idea?

I have been with this guy for 2.5 months (as his girlfriend) but we have been hanging out for 6 months total.

His family is Portuguese. He wants me to meet his family - especially his parents - who speak very broken English he has said and that he will have to translate because 98% of the time they speak Portuguese.

BTW I haven't been able to meet them due to covid and them being a little older. So no he isnt hiding me from them lol.

I want to attempt to learn a little bit of Portuguese. I know you can't be fluent overnight. But is that tacky or a good idea? I mean I like this guy. I haven't met his parents yet but they raised a good man for sure! I wanna make a kind effort and gesture. Yay? Nay?
