Enable And Disable Spell-Checking In Vim

First you choose the language which you want to use:

:setlocal spell spelllang=en_us

or

:setlocal spell spelllang=de_at

For the German spell files you have to:

emerge vim-spell-de

You can disable spellchecking with:

:set nospell

]s move to next misspelled word, [s move to prev. misspelled word z= suggests correctly spelled words under cursor, 1z= takes the first word from the suggestion list ^Xs does the same in insert mode. :spellr repeats replacements done with z= for all matches
