The Origin of Take Affect or Take Effect
The words affect and effect have different histories, although both are connected to Latin.
Affect comes through Latin afficere, which means to act on or influence something. This helps explain why affect is commonly used as a verb meaning “influence.”
Effect comes through Latin efficere, meaning to accomplish, produce, or bring about something. This connects with its common noun meaning of “result.”
The phrase take effect developed around the idea of something beginning to produce its intended result. When a law or rule takes effect, it begins to operate. When medicine takes effect, it begins to work.
This is why English uses the established phrase take effect, rather than take affect, for this meaning.
