arithmetic = arithm<number> + etic<adjective suffix>

- etic<adjective suffix>: A suffix derived from Greek -etikos, used to form adjectives (e.g., poetic, energetic).
Etymology Origin:
The word arithmetic traces back to Greek arithmētikē (tekhnē), meaning "the art of counting." The root arithm- reflects its focus on numbers, while -etic adapts it into an adjective or noun form in English. Over time, it narrowed from general calculation to the foundational branch of mathematics.
