Questions & Answers about Şirketin kurucusu yaşlı bir adam.
How exactly is the word kurucu formed here?
It comes from the verb root kur- (to found, set up, or establish). By adding the agentive suffix -ucu (which signifies 'one who does the action'), we get kurucu (founder).
Why does the agentive suffix take the form -ucu instead of -ıcı?
This suffix follows 4-way vowel harmony. Because the only vowel in the verb root kur- is an 'u', the suffix harmonizes to -ucu. If the root had an 'a' or 'ı' (like yarat-, to create), the suffix would be -ıcı (making yaratıcı, creator).
Why does the sentence use kurucusu instead of just kurucu?
It is part of a definite noun compound (a genitive-possessive construction) linking the company and the founder. Şirketin has the genitive suffix (the company's), so the possessed noun needs the 3rd-person possessive suffix. Since kurucu ends in a vowel, it takes the buffer letter s followed by the possessive -u, becoming kurucusu.
Is there a specific reason why bir comes between yaşlı and adam?
