Questions & Answers about گفتار خوب بخشی از رفتار حرفهای است.
How does the suffix in گفتار (goftâr) change the meaning of the root verb?
گفتار is formed by taking the past stem of گفتن (to say/speak), which is گفت, and adding the suffix -ار (-âr). This suffix creates a "manifestation noun"—a noun representing the visible, audible, or tangible result of an action. Here, the action of speaking becomes the noun "speech" or "discourse."
رفتار (raftâr) comes from the verb for "to go" (رفتن). How does that translate to "behavior"?
Just like گفتار, رفتار uses the past stem رفت (went) plus the -ار suffix. While it literally represents the manifestation of "going," Farsi uses this word metaphorically to describe the way someone "goes about" their life or interacts with others—hence, it means "behavior" or "conduct."
Why is there an ی at the end of بخش in the phrase بخشی از? Is it replacing the Ezafe?
The ی here is the indefinite article meaning "a" or "an." So بخش (part) becomes بخشی (a part). You do not need an Ezafe here because the preposition از (from/of) already does the job of linking "a part" to "professional behavior."
What is the function of the ای (-i) at the end of حرفهای (herfe-i)?
حرفهای is an adjective made from the noun حرفه (profession) plus the relational suffix, meaning "professional." Because ends in a silent (he), Farsi orthography requires adding an Alef/Hamza combination (written as ) to attach the suffix smoothly, rather than using a standard .
