While the above rules are standard, there are exceptions where the words take on alternative roles:
Effect as a Verb
In formal contexts, effect can function as a verb meaning to bring about or cause something.
Example:

Common Mistakes and How to Avoid Them
1. Confusing Affect (Verb) with Effect (Noun)
People often misuse effect as a verb or affect as a noun in casual contexts.
Incorrect:
- The rain will effect the picnic.
- We need to study the affects of climate change.
Correct:
- The rain will affect the picnic.
- We need to study the effects of climate change.
2. Overlooking Context
The meaning of the sentence determines which word to use. Ask: Is this a cause (verb) or a result (noun)?
Example:
- The medication affects blood pressure. (Verb: influencing)

Tips to Remember the Difference
1. Use Mnemonics
- A for Action (verb): Affect is an action word.
- E for End result (noun): Effect is the outcome.

If replacing affect with "influence" works, use affect. If replacing with "result" works, use effect.
Example:
- The storm influenced flight schedules → The storm affected flight schedules.
- The result of the storm was flooding → The effect of the storm was flooding.
3. Check the Sentence Structure
- Affect usually precedes a noun: The news affected her deeply.
- Effect often follows "of": The effect of the news was profound.
