Meaning and Definition
Comió is the third person singular form in the simple past (pretérito perfecto simple, often called pretérito) of the verb comer, which means to eat. So comió translates to he ate, she ate, or you ate when using the formal usted form. The basic definition is an action of eating completed in the past.
Nuance: The pretérito (comió) expresses a finished action at a specific time or a sequence of completed actions. It is different from the imperfect past (comía), which describes habitual or ongoing past actions. For example, compare Ella comió a las ocho with Ella comía cuando sonó el teléfono. The first uses comió to tell a completed event; the second uses comía to describe background or habitual activity.
Etymology: Comer comes from Latin comedere, from com- (together, with) + edere (to eat). Over time comedere evolved into comer in Spanish, and the past-tense stem com- led to the simple past form comió for third person singular, with the accent mark indicating the stressed vowel in the past form.

Synonyms, Antonyms, and Word Usage Differences
Synonyms: In many contexts, comer is the main verb for eat and has few exact synonyms for general use. However, other verbs can be used depending on nuance: degustar means to taste or sample, alimentarse means to feed oneself or be nourished (more formal), and merendar means to have an afternoon snack. None of these are direct one-to-one replacements for all uses of comió, but they can replace comer when the action is specific.
Antonyms: The opposite idea to comió is not eating or refraining from eating. Common expressions for opposites are no comió (he/she/you did not eat) or ayunar (to fast). For example, No comió nada means he/she/you did not eat anything. Ayunó is the past of ayunar and means he/she/you fasted.
Choosing the correct word: Use comió when you want to say someone ate in one specific, completed moment in the past. If you want to say someone used to eat often or was eating when something else happened, choose comía. Use degustó when you want to focus on tasting or sampling. Use merendó only for a snack context. Choose wording by the action type (finished action vs ongoing habit) and formality.
Pronunciation and Accent
Pronouncing comió correctly helps you sound natural. In Spanish, comió is pronounced approximately as koh-MYOH in English phonetics. The stress falls on the final syllable because of the accent mark on the o. The correct IPA is /koˈmjo/.
Breakdown: co = /ko/ as in cold without the l sound, mió = /ˈmjo/ where m + the glide /j/ with the o vowel. The accent on the o indicates that the stress must be on the last syllable, unlike comio (I eat, presente) which has stress on the first syllable and is written como technically for comer conjugations; note that there is also como (I eat) and comió (he/she/you ate) which differ by accent and therefore stress and meaning.
Common mistakes: English speakers sometimes omit the accent on written Spanish, leading to confusion between como (I eat or like) and comió (he/she ate). Another frequent error is misplacing stress: pronouncing COM-ee-oh instead of co-MYOH. Also watch for the glide: the letters i and o form the /jo/ sound rather than two separate vowels in slow speech.
Native Speaker Nuance and Usage Context
Native speakers use comió frequently in everyday talk about meals and events. It is neutral and common in both informal and formal conversation. Typical contexts include talking about what someone ate for breakfast, describing a short story where someone ate something, or answering the simple question Qué comió? (What did he/she/you eat?).
Casual conversation: In casual speech between friends, you might hear sentences like Ella comió pizza anoche — short and direct. In reply to someone asking if you want more food, a person might say Yo ya comí, meaning I already ate. This is a natural way to decline another portion.
Polite or formal contexts: Comió is also suitable in formal situations when using usted. For example, ¿Usted comió bien durante su viaje? is polite and correct. The verb form does not become informal on its own; the surrounding pronoun and tone determine formality.
Regional notes: While comió is understood throughout the Spanish-speaking world, small regional preferences influence meal names and idiomatic expressions. For example, in some countries almuerzo refers to lunch and cena to dinner; people may ask Qué comió de almuerzo? or Qué comió de cena? depending on local vocabulary. But the use of comió as past tense remains stable across regions.
Storytelling and narrative: Because the pretérito is used to describe completed actions, native speakers use comió when narrating events in sequence: Primero comió, luego salió, después llamó a su amigo. This sequencing with the pretérito makes events clear and chronological.
Conclusion
To summarize, comió is the third person singular pretérito form of comer, meaning he ate, she ate, or you ate (formal). It signals a completed action in the past, so use it when you want to describe one-time events or actions with a clear endpoint. Remember the contrast with comía, which describes habitual or ongoing past actions. Pronounce comió as /koˈmjo/ with the stress on the final syllable, and be careful to include the written accent to avoid confusion with similar words. Practicing simple example sentences and listening to native speech will help you internalize both meaning and sound. With regular use, comió will become a natural part of talking about past meals and events in Spanish, and it will help you form many common past-tense sentences quickly and accurately.
