✕Common Mistakes
Welche Unterlagen brauch ich?
In standard written German the verb needs the ending ‘-e’ – ‘ich brauche’. ‘brauch’ is colloquial and should be avoided in formal contexts.
Welche Unterlage brauch ich?
‘Unterlage’ is singular; the question asks for multiple items, so the correct plural is ‘Unterlagen’.
Welcher Unterlagen brauch ich?
Do not use the masculine singular ‘Welcher’ here; ‘Unterlagen’ is plural, so the correct form is ‘Welche’.

Cultural Tip
In formal written German (e.g., official letters or emails) always use the full verb form ‘ich brauche’. Dropping the final ‘e’ (‘brauch’) is acceptable in casual spoken conversation but can sound too informal in bureaucratic contexts. Also, remember that ‘Unterlagen’ is always plural; if you refer to a single item, use ‘das Dokument’ or ‘die Unterlage’.
