Usage tips
Word composition
The word is made up of three parts: 'voll' (complete), '-jährig' (related to years of life), and the ending '-keit', which forms a noun. So it literally means the state of having reached the full years.
EXAMPLE
Die Volljährigkeit bringt viele neue Rechte und Pflichten mit sich.
The age of majority brings many new rights and responsibilities with it.
Typical collocations
The most common and important combination is 'die Volljährigkeit erreichen' (to reach the age of majority). The prepositions 'mit' (at/with) and 'ab' (from/as of) are also often used to describe the point in time or the consequences.
EXAMPLE
In Deutschland erreicht man mit 18 Jahren die Volljährigkeit.
In Germany, you reach the age of majority at 18.
Register and usage
Although 'Volljährigkeit' (age of majority) is a legal term, it is also often used in everyday language when talking about becoming an adult. It marks an important stage of life.
EXAMPLE
Meine Tochter freut sich schon sehr auf ihre Volljährigkeit nächstes Jahr.
My daughter is already really looking forward to reaching the age of majority next year.

Volljährigkeit vs Erwachsenenalter
adulthood
'das Erwachsenenalter' and 'die Volljährigkeit' are both connected to someone becoming an adult. However, 'das Erwachsenenalter' means an entire stage of life after childhood and adolescence. It can include physical, mental, and social maturity. 'die Volljährigkeit' is more specifically legal: you reach it at a certain age, for example at 18, and receive certain rights and duties. Learners may confuse the words because both have to do with being an adult. In practice: for life as an adult, you say 'Erwachsenenalter'; for the legal status, you say 'Volljährigkeit'.
