Subjektiver Gebrauch der Modalverben
Subjektive Modalverben — for English Speakers
Introduction
German modal verbs have a 'subjective' use that expresses degrees of probability — similar to English 'must be', 'might be', 'could be'. 'Er muss krank sein' = 'He must be sick' (high certainty). 'Sie dürfte 30 sein' = 'She's probably 30' (moderate certainty). English uses the same modals for this, making the concept quite natural. The nuance levels are more granular in German, especially with 'dürfte' which has no single English equivalent.
German vs English
In German
Er muss krank sein. (He must be sick — high certainty)
In English
He must be sick.
Key Difference
Almost identical usage — modal + infinitive expressing certainty about a present state.
In German
Das könnte stimmen. (That could be right — possibility)
In English
That could be right.
Key Difference
Same modal, same meaning — both express possibility rather than ability here.
Common Mistakes for English Speakers
Er muss krank zu sein.
Adding 'zu' before the infinitive — subjective modals take a bare infinitive, no 'zu' needed.
Using 'dürfte' for permission instead of probability.
Confusing 'dürfte' (K2 of dürfen = probably) with 'darf' (may/is allowed). Context determines meaning.
Practice Examples
Das dürfte schwierig werden.
That will probably be difficult.
Er könnte Recht haben.
He could be right.
Sie muss das gewusst haben.
She must have known that.
Memory Tip
Subjective modals = certainty scale: muss (must be) > dürfte (probably) > könnte (could be) > mag (may be).
