in edition (addition) to

"In edition to" is a common slip when writers mean "in addition to." Use the version below to spot and fix the error quickly.

Quick answer

Use "in addition to" to add or include something. "In edition to" is incorrect unless you literally mean a publication's edition.

Edition = a version or issue (books, software releases).
In addition to = a connector meaning "besides" or "as well as."
Replace "in edition to" with "in addition to" when the sentence adds items; check comma placement when the phrase is parenthetical.

Core explanation - why edition ≠ addition

"Addition" comes from the verb add and forms the fixed connector "in addition to," which links or adds information. "Edition" names a version (for example, "second edition") and cannot serve as a connector.

Swapping the words either changes the meaning or creates nonsense: "the new edition to the plan" suggests a version of the plan, not an extra item added to it.

If you're listing or adding items, use in addition to.
If you mean a version or issue, use edition (e.g., "third edition").
Diagnostic examples: "In addition to the survey results, include raw responses." vs. "The second edition of the textbook includes a new chapter."

Rewrite help - fix your sentence in three quick steps

Step 1: Decide whether the sentence is adding items (connector) or naming a version (edition).
Step 2: If it's a connector, replace "edition" with "addition."
Step 3: Adjust commas: no comma when the phrase leads a tight clause; use commas when it's parenthetical.

Original: "In edition to the handout, complete the quiz." →
Rewrite: "In addition to the handout, complete the quiz."
Original: "She bought the limited edition, and in edition to that, a poster." →
Rewrite: "She bought the limited edition, and in addition to that, bought a poster."
Original: "We need laptops in edition to chargers." →
Rewrite: "We need laptops in addition to chargers."

Formatting and quick grammar notes (hyphenation, spacing, commas)

Three separate words: "in addition to" - no hyphens, single spaces.
Never hyphenate: wrong = "in-addition-to".
Comma rules: "In addition to X, Y" (lead-in). If parenthetical: "X, in addition to Y, Z."
Don't replace "edition" when you really mean a version of a publication: "third edition" is correct.

Memory trick and editing tests

Mnemonic: addition = add (think +). Edition = edition (think book or release).
Substitution test 1: Replace the phrase with "besides" or "as well as." If it still makes sense, use "in addition to."
Substitution test 2: If the sentence needs a version or issue (book, software), keep "edition."

Example: "In addition to cookies" → "Besides cookies" (works) → use addition.
Example: "The new edition of the guide" → substitution fails → use edition.

Similar mistakes to watch for

Writers sometimes mix "in addition to" with "besides" or "additionally," or use "edition" when they mean "addition."

"Besides" works informally: "Besides the cake, we bought drinks."
"Additionally" is a formal adverb often used to start sentences: "Additionally, we surveyed the team."
"Edition" is right only for versions: "limited edition," "second edition."

Compare: Informal: "Besides the budget, we considered staffing." Formal: "In addition to the budget, we considered staffing."
Wrong: "In edition to the new rules, the team updated the checklist." -
Right: "In addition to the new rules, the team updated the checklist."
