Questions & Answers about Ampulü icat eden mühendis kim?
Why does ampulü have the accusative case suffix -ü?
Ampul is the direct object of the verb icat etmek (to invent), and verbal adjectives (participles) like eden still take objects in the accusative case just like regular verbs do. Also, notice it takes -ü instead of -u; because it is a foreign loanword, the final l is soft, breaking standard vowel harmony rules.
How does eden mean "that invented"?
Eden comes from etmek (to do/make) combined with the subject participle suffix -An (which becomes -en here). Together with icat, icat eden literally means "the doing-invention one". We use this suffix to create relative clauses like "who invents" or "that invented" when modifying a noun like mühendis (engineer).
Since we are learning the passive suffix -Il, how would we use it to say "the light bulb that was invented" instead?
We would change the active helper verb etmek to its passive form edilmek. Notice how the t changes to a d before adding the passive suffix -il. Then we add the same participle suffix -en, giving us icat edilen ampul (the light bulb that was/is invented).
Does icat eden specifically mean "invented" in the past tense?
