I can form the past participles of strong verbs with stem changes, and I can ask questions in the perfect tense about a past trip or experience.
Key learning points
- Strong verbs form past participles with 'ge-' and '-en' in the perfect tense.
- Some verbs have a vowel change in their past participle, such as 'ei' → 'ie', 'ie' → 'o', 'i' → 'u' or 'e' → 'o'.
- To form a closed question in the perfect tense, swap the position of 'haben' or 'sein' with the subject.
- For open questions in the perfect tense, place a question word before 'haben' or 'sein'; the subject follows.
Words to know
- strong verb (perfect tense)
- verb whose past participle adds ‘-en’ and often changes the stem vowel, e.g., 'geflogen'
- past participle
- verb form that forms the perfect tense, together with the auxiliary verb
- closed question
- a question which can be answered with yes/no, formed by inverting the subject and verb in a sentence
- open question
- a question starting with a wh- word, followed by word order 2
Common mistakes
Verbs with inseparable prefixes do not change when forming their past participle.
Verbs with inseparable prefixes do not add 'ge-' when forming their past participle, but many do have vowel changes, e.g., 'vermeiden' becomes 'vermieden', 'empfehlen' becomes 'empfohlen'.
