Formal causality (в связи с)

Formal Causality: в связи с

In professional and formal contexts, such as business, news, and logistics, you will frequently encounter the compound preposition в связи с to say "due to" or "in connection with." This preposition always triggers the Instrumental case.

If the following word starts with certain consonant clusters (like сб-), the preposition с adds an о for easier pronunciation, becoming в связи со.

The director himself is studying the logistics due to the disruption.
Сам директор изучает логистику в связи со сбоем.

When a noun has an adjective, remember to decline the adjective into the Instrumental case as well (e.g., новая пошлина becomes с новой пошлиной).

Watch how adjectives like непредвиденный (unforeseen) or альтернативный (alternative) take Instrumental endings alongside their nouns.
