The word is made up of 'her' and 'aus'. 'Her' describes movement toward the speaker, while 'aus' indicates movement from inside to outside. So 'heraus' literally means 'out of something toward me'.
Sie rief mir aus dem Haus zu: „Komm doch mal kurz heraus!“
She called to me from the house: 'Come out here for a moment!'
In spoken language and informal texts, 'heraus' is almost always shortened to 'raus'. This short form is very common and sounds more natural in everyday speech.
Gehen wir raus an die frische Luft?
Shall we go out into the fresh air?
'Heraus' is often the separable prefix of verbs such as 'herauskommen' (to come out), 'herausschauen' (to look out), or 'herausfinden' (to find out). In a main clause, the prefix stands at the end.
Endlich kam die Sonne hinter den Wolken heraus.
Finally, the sun came out from behind the clouds.
The construction 'aus [noun] heraus' is used to emphasize the reason or motivation for an action. The noun is always in the dative.
Sie hat ihm aus reiner Freundlichkeit heraus geholfen.
She helped him out of pure kindness.
The demand 'Heraus mit ...!' (out with ...!) is a fixed expression used to forcefully ask someone to say or hand over something. The best-known form is 'Heraus mit der Sprache!' (out with it!) when someone hesitates to tell something.
Na los, heraus mit dem Geheimnis!
Come on, out with the secret!

'aus' and 'heraus' are closely related when something comes from inside to outside. 'aus' is the simple preposition and is used with the place: 'aus dem Haus' (out of the house), 'aus der Tasche' (out of the bag/pocket). 'heraus' is an adverb and emphasizes the movement outward, often toward the speaker. In the form 'aus ... heraus', 'heraus' can also emphasize a motivation or situation more strongly, for example 'aus Angst heraus' (out of fear). The words can be confused because both show an origin or an inside space. Most of the time, the rule is: 'aus' names the source, while 'heraus' makes the movement or inner reason clearer.
