marriage (wedding) anniversary

Use "wedding anniversary" to name the yearly recurrence of the wedding event. "Marriage" names the ongoing relationship or legal status and rarely collocates directly with "anniversary."

Below are concise rules, quick fixes, and many ready-to-use wrong/right sentence pairs for work, school, and casual messages.

Quick answer

"Wedding anniversary" is the standard phrase for the date of the ceremony. "Marriage anniversary" is understandable but nonstandard; use "wedding anniversary" or, when you must stress the ongoing relationship, "the anniversary of their marriage."

"Wedding anniversary" = anniversary of the wedding event (correct).
"Marriage" = the state or institution (not usually used directly with "anniversary").
If you wrote "marriage anniversary," change it to "wedding anniversary" in most contexts; use "anniversary of their marriage" for formal emphasis.

Core difference: event vs. state

An anniversary marks an event or date. The wedding is the event; marriage is the resulting state. That makes "wedding anniversary" the natural collocation.

If you need to highlight the relationship or legal status, recast the phrase: "the anniversary of their marriage" or simply "their anniversary."

Event → wedding → "wedding anniversary."
State → marriage → rephrase (e.g., "their anniversary" or "the anniversary of their marriage").
Example: Wrong: "We celebrated our marriage anniversary."
Right: "We celebrated our wedding anniversary."

Grammar and collocations that tip you off

Ask "anniversary of what?" If the answer names an event (wedding, founding, opening), pair anniversary with that event noun. Native usage favors "wedding anniversary."

Test: If the date marks the wedding, use "wedding anniversary."
In formal writing, avoid "marriage anniversary"; prefer "wedding anniversary" or "the anniversary of their marriage."
Example: Wrong: "They observed their marriage anniversary."
Right: "They observed their wedding anniversary."

Hyphenation and spacing: do you ever hyphenate or combine these words?

Use two words: "wedding anniversary." No hyphen is needed in the usual noun phrase.

Noun phrase: "their 5th wedding anniversary" - no hyphen.
Adjectival use: avoid "wedding-anniversary photo"; prefer "wedding anniversary photo" or "photo from their wedding anniversary."
Never combine into one word: do not write "weddinganniversary" or "marriageanniversary."

Memory trick and quick tests

Mnemonic: "Anniversary remembers an Event - Wedding is the Event."

Two quick tests: 1) Ask "anniversary of what?" 2) Swap "marriage" for "wedding" - if the sentence sounds natural, keep it.

If the date marks the ceremony, use "wedding anniversary."
If swapping still feels clumsy, rephrase to "their anniversary" or "the anniversary of their marriage."

Similar mistakes to watch for

Other event-vs.-state confusions follow the same pattern: pair "anniversary" with the original event (opening, founding, wedding), not with an abstract state.

Honeymoon - the trip after the wedding. Say "the anniversary of our honeymoon" if you mean that trip's date, or simply "our honeymoon was a year ago."
Nuptials - a formal synonym for wedding; prefer "wedding anniversary" over "nuptials anniversary."
Married (adjective) vs. marriage (noun): "They are married" vs. "the anniversary of their marriage" (formal).
Example: Wrong: "She wrote about the marriage anniversary of the royal couple."
Right: "She wrote about the wedding anniversary of the royal couple."
