"Don't forget to brush your hair!"

Translation: Ne forgesu brosi viajn harojn!

[AnastasiaStyIes]

Hair appears to be treated as a plural (harojn) in some sentences and as a collection (hararon) in others.

Surely this suggests both should be acceptable? Both seem logical, in any case.

[jxetkubo]

Yes, it does.

[Migranto]

I thought you could use 'la' instead of 'via' when referring to body parts?

[Oceanotti]

I seem to remember that this sentence appeared before they told us about that possibility.

[jxetkubo]

Yes, you can.
