It means that you use both lips (and no teeth). English "f" is a voiceless labiodental fricative. Labiodental means one lip plus teeth.
And thanks to the URL @dieprinzessin shared, i now have a mnemonic, too: it's always winter on Mt. Fuji.
According to the app Human Japanese (which I tried before this course was available) the F sound in Japanese is pronounced without your upper teeth touching your lower lip, which makes it sound a lot softer than English.
Yeah try making the 'f' sound by pushing air out of your mouth with rested lips instead of bringing the lips to your teeth like we do.
It kinda looks looks a person with oversized head slipping on ice and falling down.
Jocelyn and Sky I'm sorry you two were downvoted. I appreciate your comments. Our boards aren't always so serious as evidenced in the last three years.
If u ever watched anime keroro gunso the u know 2 main characters....Girl with pink hair named Natsumi (witch is simular to natsu) for summer and boy with blue hair named fuyuki (witch is simular to fuyu) for winnter
Na + tsu means fire, so by default, it seems like the other choice is better. Unless, of course, you chose to look at the drop down hint menu, then i guess that works too
Fuyu is a variety of persimmon. Maybe they're harvested in the winter? That's what I'll use to remember it though.
When it's Christmas, people bring gifts "fu-yu" (for you). Don't know if this will work for anyone in the southern hemisphere. XD
