Questions & Answers about Bunun yürekten bir özür olduğuna inanıyorum.
Isn't yürekten the ablative form meaning "from the heart"? How is it describing a noun here?
Why do we use Bunun ... olduğuna to mean "that this is"?
This is the standard way to form a "that" clause in Turkish. The subject of the embedded clause (bu) takes the genitive case to become bunun (of this). The verb (olmak) takes the -dık participle plus a possessive suffix matching the subject (-u). Literally, the structure translates to "to its being."
Why is there a dative suffix (-a) at the very end of olduğuna?
The verb inanmak (to believe) always requires the thing you believe in to take the dative case (-e/-a). Since the "thing" being believed is the entire noun clause ending in olduğu, we must add the dative suffix to it. The -n- is a buffer letter used between a possessive suffix and a case marker.
Could I say bir yürekten özür instead of yürekten bir özür?
