Learn Turkish: Genelge yürürlüğe girdiğinden dolayı, gece vardiyası uygulanmayacak. - Because the circular went into effect, the night shift will not be applied.

This uses the verb girmek (to enter) with the object participle -dik, making it a noun-like clause. It becomes girdiği (its entering). Then we add the ablative case -nden (from) to connect with the postposition dolayı (because of). Literally, it translates to 'because of its entering'.

The current lesson focuses on -dan itibaren (from ... onwards). How is -dan dolayı related?

Both itibaren (starting from) and dolayı (because of) are postpositions that require the word before them to be in the ablative case (-dan/-den). While -dan itibaren tells you when an ongoing action starts, -dan dolayı gives the reason why something happens.

What does yürürlüğe mean, and why is there an -e at the end?

The root word is yürürlük (validity, effect). The verb girmek (to enter) requires a destination marked by the dative case (-e/-a). When we add -e to mean 'into effect,' the final k in yürürlük softens to ğ. Together, yürürlüğe girmek is a common phrase meaning 'to go into effect.'

Why is it gece vardiyası instead of just gece vardiya?
