German: Expressing Strong Possibility with 'dürfte' and 'könnte'
Learn to express stronger possibility in German using 'dürfte' and 'könnte', equivalent to English 'may well' and 'could well', and distinguish them from 'wahrscheinlich'.

English uses 'may well' and 'could well' to signal that something is not only possible but quite likely. German does not translate these word-for-word. Instead, it uses the modal verbs 'dürfen' and 'können' in the subjunctive II (Konjunktiv II), most commonly as 'dürfte' and 'könnte'. This lesson teaches you to form and use these forms so you can express confident possibility without overstating certainty.
By the end, you can…
- form and use 'dürfte' to express that something is quite likely.
- use 'könnte' to suggest a strong but less certain possibility.
- distinguish 'dürfte' and 'könnte' from 'wahrscheinlich' and 'vielleicht'.
Listen once. Try it slowly. Then say it without looking.

Make it make sense
Useful pattern
German expresses strong possibility with the Konjunktiv II forms 'dürfte' (from 'dürfen') and 'könnte' (from 'können'). They behave like normal modal verbs: the modal goes in position two and the main verb goes to the end in the infinitive. Examples: 'Sie dürfte recht haben.' (She may well be right.) 'Das dürfte stimmen.' (That may well be true.) 'Er könnte im Büro sein.' (He could well be at the office.) 'Das könnte teuer werden.' (That could well get expensive.)
When to use it
Use 'dürfte' when you have good reasons for an assumption and want to sound confident but not absolute. Use 'könnte' when the possibility is strong but you are less sure, or when you want to soften a warning or suggestion. Compare: 'Sie ist wahrscheinlich zu Hause.' (She is probably at home — a straightforward probability statement.) 'Sie dürfte zu Hause sein.' (She may well be at home — a modal, slightly more cautious assessment.) 'Sie könnte zu Hause sein.' (She could well be at home — possible, but less committed.)

In German-speaking countries, 'dürfte' and 'könnte' are especially useful in professional and polite contexts because they allow you to express a strong opinion without sounding overconfident. They are common in meetings, customer service and academic writing. In casual conversation, 'wahrscheinlich' is also frequent, but 'dürfte' often sounds more considered and diplomatic.
One thing to watch for
Using 'dürfen' in the present indicative to mean 'may well': 'Sie darf recht haben.'
Try this instead: Use the Konjunktiv II form 'dürfte': 'Sie dürfte recht haben.' The indicative 'darf' means 'is allowed to', not 'may well'. Similarly, use 'könnte', not 'kann', for 'could well': 'Er könnte im Büro sein.'

Try answering out loud before checking a possible answer.
1Translate: 'That may well be true.'
Show a sample answer
Das dürfte stimmen.
'dürfte' is the Konjunktiv II of 'dürfen' and expresses a strong, well-founded assumption. 'Das könnte stimmen' is also possible but slightly less confident.
2Which form is more confident: 'dürfte' or 'könnte'?
Show a sample answer
'dürfte' is generally more confident.
'dürfte' suggests a well-founded assumption, while 'könnte' presents a strong possibility with less commitment. Context can shift the nuance, so both can overlap.
3Correct the error: 'Er darf im Büro sein.'
Show a sample answer
Er könnte im Büro sein. (or: Er dürfte im Büro sein.)
'darf' means 'is allowed to'. For 'could well be', use 'könnte'; for 'may well be', use 'dürfte'. Both are Konjunktiv II forms.
Use 'dürfte' for confident, well-founded assumptions and 'könnte' for strong but less certain possibilities. Both are Konjunktiv II forms and translate English 'may well' and 'could well' far better than 'vielleicht' or 'wahrscheinlich'.
