The rules for hyphenating noun phrases, especially compound modifiers, like “as-told-to essay.”
General Rule: Use hyphens in compound adjectives before a noun.
When two or more words work together as a single adjective modifying a noun, you hyphenate them.
Examples:
-
well-known author (but: the author is well known)
-
full-time job
-
once-in-a-lifetime opportunity
-
as-told-to essay = an essay that is told (or narrated) by someone to a writer, not authored solo
Rule Application in Your Example:
“This as-told-to essay is based on a transcribed conversation…”
Here, "as-told-to" acts as a compound adjective modifying “essay,” so it’s correctly hyphenated.
Without the hyphen, "as told to essay" would be grammatically jarring—like a noun + clause mash-up.
Don’t hyphenate when:
-
The phrase follows the noun.
-
Correct: The essay is as told to the writer.
-
Incorrect: The essay is as-told-to the writer.
-
-
The first word ends in -ly (adverb + adjective).
-
highly-recommended book → highly recommended book
-
Tips:
-
Use a hyphen if misunderstanding is possible.
-
A “small business owner” ≠ a “small-business owner.”
-
-
When in doubt, test if the phrase answers "what kind of ___?"
-
What kind of essay? → An as-told-to essay.
common hyphenated noun phrases (compound modifiers) often used in business writing, journalism, and professional communication.
