How is the noun tābesh (shining) formed from a verb here?
It is an action noun formed by taking the present stem of the verb tābidan (to shine), which is tāb, and adding the suffix -esh. This is a very common way to turn an action into a noun in Farsi.
Why is it tābesh-e āftāb when there is no written word for 'of'?
This is the ezafe in action! In Farsi, you link a noun to its possessor (the sun) by adding a short 'e' sound to the end of the first word. It is rarely written out, but it acts just like the English 'of', making it 'the shining of the sun'.
What is the difference between āftāb and khorshid, since they both mean 'sun'?
Khorshid refers to the physical sun in the sky as a star. Āftāb refers more to the sunlight, the sunshine, or the warm rays hitting the earth. Since this sentence is about the beautiful glow on the water, āftāb is the natural choice.
Why does the word for 'on' (ru) have a 'y' sound added to it in ruy-e daryā?
The word ru literally means 'surface' or 'face'. When used as a preposition meaning 'on top of', it needs an ezafe to connect to the next word (the sea). Because ru ends in a long vowel, we add a 'y' sound to bridge the gap smoothly, making it ruy-e.
