The phrase take effect has existed in English for hundreds of years. It combines the verb take, meaning “to begin,” with the noun effect, meaning “result” or “outcome.” Together, the phrase means that something starts producing its intended result.

The confusion comes from the words affect and effect.

Affect comes from the Latin afficere, meaning “to influence.”
Effect comes from the Latin effectus, meaning “result” or “accomplishment.”
