Learn Dutch: De jongen kruipt door de groene struik heen. - The boy crawls through the green bush.

While door by itself means "through," adding heen emphasizes the continuous movement or path completely through an obstacle from one side to the other. It makes the action of navigating entirely through the bush more vivid.

Why is heen placed at the very end of the sentence?

The phrase door ... heen is a circumposition, meaning it is a two-part preposition that wraps around its object. The first part (door) goes before the noun phrase (de groene struik), and the directional part (heen) goes right after it.

Why does groene have an -e at the end?

Because struik is a de word (de struik). As a quick refresher: when an adjective comes directly before a noun and is preceded by de, the adjective gets an -e added to its base form (groen).

What is the infinitive of kruipt?

The infinitive is kruipen, which means "to crawl" or "to creep." Because the subject is de jongen (a third-person singular subject like "he"), we take the stem of the verb (kruip) and add a -t to make kruipt.
