"We do not live in Japan anymore."
Translation:Me emme asu enää Japanissa.
Asua is the basic form of the verb. But when you negate it, it becomes asu: minä en asu, sinä et asu, etc.

They = literally one volunteer (not me). The Tips will come, but I definitely think it's worth looking up things elsewhere, too. I particularly like Wiktionary and uusikielemme.fi, but sometimes just using a search engine also works well. With some of the courses I've done here, the Tips just didn't work for me anyway (I saw them but didn't understand them), although they existed.
