The verb "küssen" is conjugated in second person singular, plural and in the third person with 'ß'

du küßt
er/sie/es küßt
ihr küßt

Is it incorrect if I use it for the others too? Also, why is it not "küßen" to begin with? Isn't any word with 'ss' allowed to be replaced by 'ß'?

It is spelled with double s in every case.

Have a look the answer to the question Is there a rule that dictates whether to use the eszett (scharfes S) or double s?.

    It seems like that website still uses the old rules. The new (1996) rules are simple: Short vowel is followed by double s instead of ß.

  • Don't forget diphthongs. They are aloways followed by ß. Nov 29, 2012 at 12:37

    There are no short diphtongs, aren't there? So "diphtongs are always followed by ß" ist more of a corollary than an additional rule.
