Please be patient

Our volunteers look into many questions every day; sometimes it takes them a little while to answer.

Pro tip: you can rename the thread title with `.tr <thread name>`

Make it descriptive, including relevant context, but also to the point. This way you improve your chances of getting a more relevant and specific answer.

vivant is the adjective "alive", so it would be correct (it can also be a noun in rare occasions, but not here)
vivre is the verb "to live" indeed, it doesn't fit here

your sentence works

that said, if you're talking to your sister, you have to use the feminine version

I forgot about that. 💀 what would be the feminine version?

[shadow copper]

vivante

Thank you!

you can also say "tu es en vie", which is more "alive" as opposed to "living"
