Questions & Answers about گیاهان به تابش نور نیاز دارند.
How is the action noun تابش formed from its verb?
It comes from the verb تابیدن (to shine). If you take its present stem, which is تاب, and add the suffix ـِش (-esh), you get تابش (shining). This suffix is heavily used to turn verbs into nouns that describe the action.
Why is there a به before تابش?
The compound verb نیاز داشتن (to need) pairs with the preposition به (to). You do not just need something in Farsi; you have a need to something. That is why به appears right before the thing being needed.
Why does the word for plants (گیاهان) use the plural suffix ان instead of the usual ها?
The suffix ان is traditionally used for people and living things, including plants and trees. While you could technically say گیاه ها, using ان is much more common and natural for this specific word, especially in writing.
How are the words for shining and light linked together in speech?
They are linked by an invisible Ezafe vowel. You pronounce it as tabesh-e nur. This connects the action noun تابش to the noun نور to show possession or association, literally meaning the shining of light.
