Usage tips
Word family
The adjective 'ursächlich' (causal) is derived directly from the noun 'die Ursache' (the cause). It helps to remember both words together, since they have the same basic meaning.
EXAMPLE
Die Ermittler suchen nach der Ursache für den Brand.
The investigators are looking for the cause of the fire.
Register and style
'Ursächlich' (causal) is a formal word. It is often found in reports, scientific texts, or administrative language to name a clear reason for something.
EXAMPLE
Der Bericht nennt menschliches Versagen als ursächlichen Faktor.
The report names human error as a causal factor.
Use with 'für'
'Ursächlich' is very often used in the construction 'ursächlich für etwas sein' (to be causal for something). The preposition 'für' introduces the consequence or result.

The strong current was causal in the boat capsizing.
Typical collocations
Besides being used with 'sein' (to be), 'ursächlich' is often combined with verbs such as 'zusammenhängen' (to be connected). The combination 'der ursächliche Zusammenhang' (the causal connection) is also very common.

ursächlich vs verantwortlich
responsible
'verantwortlich' and 'ursächlich' can both express that something is the reason for a result. In this meaning, 'verantwortlich' is often used for negative consequences, and it sometimes sounds like assigning blame. 'ursächlich' is more objective and more formal. It simply describes that there is a direct connection between cause and effect. In everyday language, people are more likely to say 'dafür verantwortlich' (responsible for that). In reports, medicine, technology, or official texts, 'ursächlich' sounds more precise and more neutral.
ursächlich
Die Ärztin prüft, ob die neue Medizin ursächlich für die Beschwerden ist.
The doctor is checking whether the new medicine is the cause of the symptoms.
verantwortlich
