'Nachahmen' (to imitate) is a separable verb. The prefix 'nach-' goes at the end of the main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.

Small children often imitate their parents.
The verb 'nachahmen' (to imitate) always requires an accusative object. You ask: Whom or what is someone imitating?

The context reveals the exact meaning. If the object is a person or animal, it is about behavior or voice. If the object is a product or work of art, it is about creating a copy.

When it is about copying behavior, 'nachahmen' (to imitate) is often used with objects such as 'die Stimme' (the voice), 'die Bewegungen' (the movements), 'die Gesten' (the gestures), or 'den Akzent' (the accent) of a person.

to copy
'kopieren' and 'nachahmen' can both mean that you take something from someone or from an original. 'kopieren' puts more emphasis on making something as similar as possible, for example a style, an idea, or a text. 'nachahmen' is especially suitable for behavior, voice, movements, or a way of acting. It can also be used for products or works of art when they are meant to look like an original. In everyday language, 'nachahmen' often sounds more natural when the focus is on people or animals. 'kopieren' sounds more precise when the result is meant to be like a copy.
