Questions & Answers about Bu palto beyefendiye ait olmalı.
Why does beyefendi have the -ye ending before ait?
The word ait is a postposition meaning 'belonging to'. It always requires the preceding noun or pronoun to take the dative case (the directional 'to/for' case). Since beyefendi ends in a vowel, we add the buffer letter y followed by the dative suffix -e, creating beyefendiye ait.
Does olmalı imply a strict rule or obligation here?
No, in this context it expresses a strong logical deduction. While the -malı / -meli suffix often shows obligation ('must' or 'should'), when attached to olmak (to be) it is frequently used to say 'it must be' in the sense of 'I strongly deduce that it is'.
How is beyefendiye ait different from beyefendinin?
Both express ownership, but with slightly different emphasis. Beyefendinin paltosu uses the standard genitive case and translates to 'the gentleman's overcoat'. Using the dative plus ait acts more like an adjective phrase meaning 'belonging to the gentleman', emphasizing the fact of ownership itself.
