unavoidable
Something that cannot be avoided or bypassed because it is absolutely necessary or inevitable.

The word is a negation. It is made up of 'un-' (not), the verb 'umgehen' (to avoid / to bypass), and the ending '-lich'. Something 'Unumgängliches' is therefore literally something you 'nicht umgehen' (cannot avoid).

'Unumgänglich' is very often used predicatively with the verb 'sein' (to be) or 'werden' (to become). The structure is then: 'Etwas ist/wird unumgänglich' (Something is/becomes unavoidable).
