German Phrase
Bitte fülle dieses Formular aus.
Meaning
A polite request asking someone to complete a specific form. The phrase combines the courtesy word 'Bitte' with the du‑imperative of the separable verb 'ausfüllen'.
When to use
Use this sentence when you are speaking informally (du) to a colleague, a friend, or a customer you know well, and you need them to fill out a paper or digital form. In offices, schools, or online portals you’ll often hear a more formal version with 'Sie'.
✦Grammar Breakdown
BittefüllediesesFormularaus
Bitte (polite particle)
Used at the beginning of a request to make it courteous; it does not affect verb conjugation.
füllen (separable verb)
The verb 'ausfüllen' splits in the sentence: the stem 'fülle' appears in the imperative, and the prefix 'aus' moves to the end.
dieses (demonstrative pronoun)
Accusative neuter form of 'dieser', matching the noun 'Formular' which is neuter.
Formular (neuter noun)
A neuter noun meaning 'form' or 'questionnaire'; takes the article 'das' in the nominative/accusative.
Imperative du‑form
The verb is conjugated for the informal 'du' (fülle). In formal situations you would use 'Füllen Sie …'.

Gern, ich mache das gleich.
Sure, I’ll do it right away.
✕Common Mistakes
Bitte fäll dieses Formular aus.
The verb stem must be 'fülle' (with an umlaut) in the du‑imperative; 'fäll' is a misspelling.
Bitte fülle dieses Formular ausfüllen.
In the imperative the separable prefix must be placed at the end, not attached to the verb.
Bitte fülle das Formular aus.
When you want to point to a specific form, 'dieses' is more precise than the generic article 'das'.
Bitte füllen Sie dieses Formular aus.
If you keep the du‑imperative, you must not add the formal 'Sie' pronoun; that mixes registers.
↔Alternatives

Cultural Tip
German distinguishes clearly between informal (du) and formal (Sie) address. The sentence you’re learning uses the informal du‑imperative, which is appropriate with friends, peers, or when a business explicitly invites a casual tone. In most official settings (banks, government offices, hospitals) you should switch to the formal version: 'Füllen Sie bitte dieses Formular aus.' Also, remember that separable prefixes like 'aus' always move to the end of the clause in main sentences.
