The words "effect" and "impact" are often confused, but they have distinct meanings. "Effect" usually refers to the result or consequence of an action or event, while "impact" suggests a stronger, more forceful consequence, often involving significant change. Think of "effect" as a ripple in a pond and "impact" as a large rock thrown into the same pond.

Let's look at some examples to clarify the difference:

• Effect: The medicine had a calming effect on the patient. (The medicine resulted in calmness.)

• Impact: The new law had a significant impact on the environment. (The new law caused a substantial environmental change.)

• Effect: The rain had a negative effect on the picnic. (The rain resulted in a bad picnic.)

• Impact: The hurricane's impact was devastating. (The hurricane caused catastrophic damage.)

Notice that "effect" can be used as a noun or a verb (to effect change). However, "impact" is primarily used as a noun, describing the consequence of something. While you might say something has an impact, it's less common to use "impact" as a verb in everyday conversation.

Here is another example to highlight the subtle differences:

• Effect: The new policy will effect a significant change in the company's structure. (The new policy will cause a change)

• Impact: The new policy will have a significant impact on the company's productivity. (The new policy will lead to a substantial change in productivity)

In short, while both words describe consequences, "impact" generally describes something more powerful, noticeable and transformative. Choosing between the words depends on the nuance you want to convey and the strength of the result or consequence you are describing.
