Usage tips
Word structure
The word is made up of 'gegen' (against / toward) and 'Seite' (side). It describes an action that goes from one side to the other and back again, so it is based on reciprocity.
EXAMPLE
Gegenseitiges Verständnis ist die Basis einer guten Beziehung.
Mutual understanding is the basis of a good relationship.
Use with reflexive pronouns
'Gegenseitig' (mutual / each other) is very often used together with a plural reflexive pronoun (uns, euch, sich). It emphasizes that the action is reciprocal: A does it for B and B does it for A.
EXAMPLE
Wir helfen uns gegenseitig bei den Hausaufgaben.
We help each other with homework.
Typical collocations
Common verbs combined with 'sich gegenseitig' (each other / one another) are: unterstützen (to support), helfen (to help), inspirieren (to inspire), respektieren (to respect), and vertrauen (to trust).
EXAMPLE

gegenseitig vs sich
oneself / each other
'sich' and 'gegenseitig' can both express that two or more people do something for each other. In this meaning, 'sich' often means 'einander' (each other), for example 'Sie helfen sich' (They help each other). 'gegenseitig' makes this reciprocal relationship clearer and stronger: both sides do or feel something for each other. Learners may confuse the words because both can appear in similar sentences. However, 'sich' is a pronoun and belongs grammatically to the verb. 'gegenseitig' describes the relationship more precisely and can often be added for clarity.

sich
