effect
English
Etymology
For noun: from Old French effect (modern French effet), from Latin effectus (“an effect, tendency, purpose”), from efficiō (“accomplish, complete, effect”); see effect as a verb.
For verb: partly from Latin effectus, perfect passive participle of efficiō (“accomplish, complete, do, effect”), from ex (“out”) + faciō (“do, make”) (see fact and compare affect, infect) and partly from the noun effect.

- “...new governing coalitions have effected major changes” indicates that major changes were made as a result of new governing coalitions.
- “...new governing coalitions have affected major changes” indicates that before new governing coalitions, major changes were in place, and that the new governing coalitions had some influence over these existing changes.
