ärritusest

ärritusest is the elative singular form of the Estonian noun ärritus, which means irritation or annoyance. The elative case marks source, origin, or cause, so ärritusest translates roughly as “from irritation” or “out of irritation.” This form is used when a reaction or symptom is attributed to irritation.

In regular Estonian usage, ärritusest appears in medical, dermatological, or descriptive contexts to indicate that something arises from irritation. For example, Sümptomid võivad tekkida ärritusest. translates to “Symptoms may arise from irritation.” The elative is one of several cases that describe relation to or source of something, and it is more common in formal or precise language than in casual speech.
