'Sketch' is a word from English and is pronounced similarly in German. It has kept both of its English meanings: a short scene and a quick drawing.
Sein Sketch über den Alltag im Büro war sehr treffend.
His sketch about everyday office life was very apt.
You can tell from the context whether a funny scene or a drawing is meant. Words like 'aufführen' (to perform), 'Show' (show), or 'lustig' (funny) point to the theater scene, while 'zeichnen' (to draw), 'Designer' (designer), or 'Entwurf' (draft) indicate the drawing.
Die Schauspieler probten einen neuen Sketch für die Abendshow.
The actors rehearsed a new sketch for the evening show.
When it is about a funny scene, a sketch is often 'aufgeführt' (performed), 'gezeigt' (shown), or 'gespielt' (acted/performed). You can also 'einen Sketch schreiben' (write a sketch).
In der Sendung werden jede Woche mehrere Sketche aufgeführt.
Several sketches are performed on the show every week.
When a drawing is meant, a sketch is often 'angefertigt' (made/produced), 'gezeichnet' (drawn), or 'gemacht' (made). It often serves as an 'erster Entwurf' (initial draft).
Die Künstlerin hat schnell einen Sketch von der Landschaft angefertigt.
The artist quickly made a sketch of the landscape.
number
'die Nummer' and 'der Sketch' can both be part of a performance. 'die Nummer' is more general and means an individual act, for example dance, music, acrobatics, or comedy. 'der Sketch' is more specific: it is a short, funny scene with a small plot. Learners may confuse the words because a sketch in a show can also be an act. But not every act is a sketch. When you mean a funny acted-out scene, 'Sketch' is more precise.
