Samoan

Hi, I just finished unit 4 and unit 6. I noticed that 'Alu i fafo' means 'Go outside' and 'i fafo' means 'outside'. What's the difference?

how do i say good job in samoan?

I’m struggling to know the difference

I keep mixing up mumu and vevela, I think mumu is red and vevela is hot, is that right?

I keep mixing up 'O ai lenei?' and 'O ai lou igoa?'. Like, I know one means "Who is this?" and the other is "What's your name?", but in my head it's all just "who/what is this person?" 😩. Anyone else have trouble with these in Unit 1 and 5?

Ive tried many apps bc my father doesn't teach me Samoan and I want to be the first child to speak Samoan and pass it down. Ive tried lots of apps but eventually forget or get too busy
