Mora da je tako: how Serbian measures confidence

The same words that talk about duty also measure how sure you are that something is so. Different job, and mixing the two is costly. For example: “Мора да је заборавио на састанак” — He must have forgotten about the meeting. A rule from the Serbian course: worked out on examples, not memorized as a wording.

How it works

The same words that talk about duty also measure how sure you are that something is so. Different job, and mixing the two is costly.

The top of the scale is mora da. Mora da je zaboravio na sastanak does not mean he is obliged to forget. It means he must have forgotten. The shape is frozen: mora da plus a personal verb.

Below it sit sigurno and svakako: Sigurno dolazi. Then the neutral verovatno: Verovatno je kod kuće. Beside it stands valjda, which carries hope: Valjda će biti dobro.

The middle is možda: Možda će padati kiša. The bottom is teško da: Teško da će stići na vreme. And sumnjam da means "I doubt that", not "I suspect".

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
