In contrast to English's simple addition of "s" to make a noun plural, German uses several different inflections depending on the word. They fall into seven types:
#;1. No change — :der '''Lehrer''' (teacher) → die '''Lehrer'''#;2. No ending, with Umlaut — :der Apfel (apple) → die '''Ä'''pfel#;3. Add -e — :das Jahr (year) → die Jahr'''e'''#;4. Add -e, with Umlaut — :die Hand (hand) → die H'''ä'''nd'''e'''#;5. Add -er, with Umlaut — :das Tal (valley) → die T'''ä'''l'''er'''#;6. Add -n or -en — :die Frau (woman) → die Frau'''en'''#;7. Add -s — :das Auto (car) → die Auto'''s'''
