Usage tips
Word structure
The word is made up of 'ander-' (as in 'andere' (other)) and the ending '-weitig'. The ending expresses a relationship or area, so 'anderweitig' literally means 'in another area' or 'in another direction'.
EXAMPLE
Da das Restaurant voll war, mussten wir uns anderweitig nach einem Abendessen umsehen.
Since the restaurant was full, we had to look elsewhere for dinner.
Adverb or adjective
'Anderweitig' can be used as an adverb (unchanging) or as an adjective (changeable). As an adverb, it describes a verb; as an adjective, it stands before a noun and is declined.
EXAMPLE
Ich kann heute nicht, ich bin anderweitig beschäftigt.
I can't today; I'm otherwise occupied.
Register and style
This word belongs more to formal or professional language. It is often used in business emails or official rejections.
EXAMPLE
Leider ist die Position bereits anderweitig vergeben worden.
Unfortunately, the position has already been filled elsewhere.
Typical collocations
In the meaning of 'already busy', 'anderweitig' is very often used in the fixed combinations 'anderweitig beschäftigt sein' (to be otherwise occupied) or 'anderweitig verpflichtet sein' (to be otherwise committed).
EXAMPLE
Der Professor kann Sie heute nicht empfangen, er ist anderweitig verpflichtet.
The professor cannot see you today; he is otherwise committed.

anderweitig vs sonst
otherwise / else
'sonst' and 'anderweitig' can both point to another possibility. However, 'sonst' is much more common and is especially used for consequences: 'Komm pünktlich, sonst verpassen wir den Zug.' (Come on time, otherwise we'll miss the train.) It is also used in questions when asking about something additional: 'Brauchst du sonst noch etwas?' (Do you need anything else?) 'anderweitig' sounds more formal and more often means 'in another way', 'in another place', or 'for another purpose'. It also fits when someone is already otherwise occupied. The words can be confused because both express something alternative. In warnings and simple everyday questions, 'sonst' is usually more natural; in factual sentences about other possibilities, 'anderweitig' is more precise.
anderweitig
Julian kann morgen nicht helfen, weil er anderweitig beschäftigt ist.
Julian can't help tomorrow because he is otherwise occupied.
sonst
Nimm einen Regenschirm mit, sonst wirst du auf dem Heimweg nass.
Take an umbrella with you, otherwise you'll get wet on the way home.
