Congratulate on vs. Congratulate for – Which is Correct?

Both “congratulate on” and “congratulate for” are grammatically possible, but they are not equally natural. Use “congratulate someone on” for an achievement, success, or occasion. Use “congratulate someone for” mainly when praising an action or quality, especially in informal American English. In many situations, “on” is the safest choice.

Congratulate on or for – Which is Correct?

Congratulate on is the standard and most widely accepted construction when identifying what someone achieved or experienced: “I congratulated her on her promotion.” Congratulate for can also be correct, particularly when emphasizing the person’s action, effort, or conduct: “We congratulated him for speaking up.” However, many editors prefer congratulate someone on doing something even in this context.

The preposition on typically introduces the achievement, event, or occasion. The preposition for typically highlights the action or reason for praise. Because these meanings overlap, “congratulate someone on” works in more situations and is generally the best choice in formal writing.

The Best Trick to Remember the Difference

Use this simple distinction: on the achievement, for the action. If you are congratulating someone on a promotion, victory, graduation, marriage, or award, choose on. If you are praising someone for acting courageously, working hard, or making a good decision, for may fit. When uncertain, choose on.

Word	Part of Speech	Meaning	Example
on	Preposition	Identifies an achievement, event, or occasion	I congratulated Maya on her promotion.
for	Preposition	Highlights an action, effort, or reason for praise	They congratulated him for helping the team.

How to Use on

Use congratulate someone on something when the object is an accomplishment, milestone, award, change in status, or important event. This is the conventional pattern in both formal and casual English. The object after on may be a noun, noun phrase, or gerund phrase.

Examples include congratulating someone on a new job, on winning a competition, on graduating, or on reaching a personal goal. The person receiving congratulations normally appears between congratulate and on.

Example 1: The manager congratulated Priya on her outstanding presentation.

Example 2: We congratulated our neighbors on the birth of their daughter.

Example 3: Please congratulate Daniel on completing his first marathon.

Etymology of the word on

On comes from Old English on and is related to similar words in other Germanic languages. Its original sense commonly indicated physical position or contact. Over time, it developed many abstract uses, including marking an occasion, achievement, or subject of congratulations.

How to Use for

Use congratulate someone for something when you want to emphasize the action, behavior, effort, or quality that deserves praise. This construction is valid, but it is less consistently preferred than congratulate someone on. It is especially common when the complement is a verb ending in -ing, such as for speaking, for volunteering, or for persevering.

In careful or formal writing, on is often the safer preposition, even when the sentence describes an action. For example, “I congratulated her on speaking honestly” is widely accepted and may sound more natural to many readers than “I congratulated her for speaking honestly.”

Example 1: The coach congratulated the players for working together under pressure.

Example 2: I congratulated Elena for having the courage to challenge the decision.

Example 3: The committee congratulated the volunteers for organizing the event so efficiently.

Etymology of the word for

For comes from Old English for, meaning “before,” “for the benefit of,” or “because of.” It is related to forms found in several Germanic languages. Its modern uses include expressing purpose, benefit, duration, exchange, and the reason connected with an action or judgment.

Related Concepts

Understanding verb-preposition patterns makes it easier to choose between on and for after congratulate. Meaning, emphasis, and formality all influence the most natural choice.

• Verb-preposition collocations: Some verbs commonly pair with particular prepositions, such as “depend on,” “apologize for,” and “congratulate on.” These combinations are often learned as fixed patterns.
• Gerunds: A verb ending in -ing can function as a noun, as in “congratulate her on winning.” Both on and for may appear before an action in some contexts, but on remains the more broadly preferred choice.
• Achievement versus action: An achievement is the result or milestone, while an action is what a person did. “On” commonly points to the achievement; “for” can draw attention to the action.

Examples from Media and Literature

The following examples reflect the kinds of contexts in which these constructions commonly appear in public writing and everyday speech.

• News reporting: A report about an athlete’s victory may state that officials congratulated her on winning the championship.
• Business communication: A company announcement may congratulate an employee on receiving a promotion or reaching a service milestone.
• School and university writing: A graduation message may congratulate students on completing their studies.
• Film and television dialogue: A character may say, “Congratulations on the new job!” when responding to another character’s good news.
• Personal correspondence: A friend may be congratulated for standing up for someone, although “congratulated on standing up for someone” is also natural and often preferred.
