German eating -Why is "isst" not "ißt"
Why is "isst" not "ißt"
Considering it is a double S?
In German (well, generally), a vowel is long before a single consonant, and short before a doubled one.
For these purposes, "ß" is counted as single "s", as normally "s" would be pronounced like an English "z" between vowels; "ss" is its doubled equivalent. So, "isst" is spelt with a a doubled "s" to keep make it clear that the "i" is short. Hope this helps :)
They had a spelling reform in the 90s so a lot of words with esett became ss.
