Usage tips
Separable verb
'Herausstellen' (to turn out / emphasize / put outside) is a separable verb. The prefix 'heraus-' comes at the end of the main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
EXAMPLE
Er stellt die Pflanzen bei gutem Wetter heraus.
He puts the plants outside when the weather is good.

herausstellen vs betonen
to emphasize / stress
'betonen' and 'herausstellen' can both mean that you show something to be important. 'betonen' is used very often in conversations, texts, or speeches when you explicitly say that something is important. 'herausstellen' sounds a bit more matter-of-fact and often means that you put a point especially in the foreground, for example in a report, presentation, or discussion. 'betonen' is more general and more direct. 'herausstellen' fits better when a particular advantage, difference, or result is meant to be made clearly visible.
