Questions & Answers about Der Rost ist vom Oldtimer entfernt worden.
Why does this sentence use ist ... worden instead of hat ... geworden?
This sentence is in the Present Perfect Passive (Perfekt Passiv). To form the passive in the perfect tense, German uses sein as the helper verb (here, ist) rather than haben. Also, the past participle of werden drops its ge- and becomes just worden when used as an auxiliary verb for the passive voice.
Does Oldtimer refer to an old person here?
No, der Oldtimer is a classic example of a pseudo-anglicism (an English-sounding word that has a different meaning in German). It refers specifically to a classic or vintage car. An older person is usually called ein Senior or ein älterer Mensch.
Why is the past participle entfernt and not geentfernt?
The verb entfernen starts with the inseparable prefix ent-. Verbs with inseparable prefixes (such as be-, emp-, ent-, er-, ver-, zer-) never add the ge- prefix when forming their past participle.
Why use vom instead of aus dem for removing the rust?
