Expert writing Tips
Best practice
Avoid using "an after" in formal writing. Instead, opt for grammatically correct alternatives such as "a subsequent" or rephrase the sentence for clarity. For example, instead of "an after dinner drink", say "a drink after dinner".
Common error
A common mistake is to use "an" before "after" due to the vowel sound, but it's generally incorrect unless it's part of a compound word like "afternoon" or "aftermath". Always check for correct usage in context; it's generally better to say "a subsequent" or rephrase entirely.

FAQs
Is the phrase "an after" grammatically correct?
No, the phrase "an after" is generally not grammatically correct in standard English. It's usually better to use "a subsequent" or rephrase the sentence entirely.
What are some alternatives to using "an after" in a sentence?
