fuss with the vowel sound much like in fool

Foos

"Foos". That symbol has recently been replaced by just 'ss' in German. Means foot, by the way.

Fooss

the u sounds like the oo in "too"

and the ß sounds like the ss in "class"

heibst!

foos

fooose

'foosss'...but the 'u' is probably umlauted (two dots over it) so it would be closer to 'few-ssss'. means 'foot' i believe...
