Stuur alleen complete bestellingen terug.

Yes. Stuur is the imperative form of sturen and means send as a command.

Dutch often leaves out the subject in commands, just like English does in Send it back. The implied subject is you.

So Stuur alleen complete bestellingen terug is telling someone: Send back only complete orders.

Because terugsturen is a separable verb in Dutch.

The full dictionary form is terugsturen = to send back / return. But in a main clause or command, the prefix terug usually separates and moves to the end:

• Ik stuur de bestelling terug.
• Stuur de bestelling terug.

When the verb stays together, that is usually in forms like the infinitive or past participle:

• Ik wil de bestelling terugsturen.
• Hij heeft de bestelling teruggestuurd.

Alleen means only.

In this sentence, it most naturally limits complete bestellingen. So the idea is: send back only orders that are complete.

Its position matters. In Stuur alleen complete bestellingen terug, alleen comes right before the noun phrase it is restricting, which is a very common Dutch pattern.

Because Dutch, like English, can use a bare plural for a general meaning.

Complete bestellingen means complete orders in a general sense, not the complete orders. If you said de complete bestellingen, you would be referring to specific complete orders that are already known from context.

So here, no article is needed.

The basic adjective is compleet.

When a Dutch adjective comes before a noun, it often takes an extra -e ending. Since bestellingen is a plural noun, the adjective normally gets that ending:

• een complete bestelling
• complete bestellingen
• de complete bestelling

So compleet becomes complete here because of normal adjective inflection.

The singular is bestelling, meaning order.

The plural is bestellingen, formed with -en, which is a very common plural ending in Dutch.

So:

• de bestelling = the order
• de bestellingen = the orders

Often yes, but literally it means send back.

In many situations, English would use return, while Dutch naturally uses terugsturen. So in a sentence like this, terugsturen is a very normal way to express returning an order.

Depending on context, return in English may sound slightly broader, while terugsturen emphasizes the idea of sending something back.

Yes. The plain imperative Stuur ... terug is normal for instructions, manuals, workplace directions, or informal commands.

If you want a more polite or formal version, you could say:

• Stuurt u alleen complete bestellingen terug.

That adds u, the formal you, and uses the matching verb form. The meaning stays the same, but the tone is more polite.

The given word order is natural and clear.

A useful way to see it is:

• Stuur = command verb
• alleen complete bestellingen = direct object
• terug = separated verb prefix

Dutch often places the main verb first in commands, keeps the object in the middle, and puts the separable prefix at the end. So Stuur alleen complete bestellingen terug is exactly the kind of order you should expect.
