Meaning and Definition
The basic meaning of completan is they complete or you-all complete, depending on the subject. It is the third person plural present indicative of completar. In other words, it describes an action that a group of people or things does now or regularly. The verb completar means to finish, to make whole, or to fill up. It can refer to completing a task, filling in missing parts, or reaching a finished state.
Common nuance: When native speakers use completan, they usually refer to finishing something that was started or making something whole. The tone is neutral and factual; there is no implication of hurry or emotion unless context adds it. For example, completan el proyecto is simply they complete the project.
Etymology: Completar comes from the Latin completare, built from com- meaning together and plēre meaning to fill. This origin explains why completar can mean both to finish and to fill up something that was missing.

Synonyms, Antonyms, and Word Usage Differences
Synonyms: terminar, finalizar, concluir. These verbs are often interchangeable with completar, but there are slight differences. Terminar focuses on the end of an action. Finalizar is slightly more formal and often used in professional or written contexts. Concluir emphasizes reaching a conclusion or result.
Example difference: Ellos terminan la película and Ellos completan la película can both be used, but completar might suggest finishing all parts or episodes of a series, while terminar simply means finishing watching it at that moment.
Antonyms: empezar, comenzar, iniciar. These words mean to start rather than finish. If you want to say a group starts something, use empiezan or comienzan instead of completan.
Choosing the correct word: If you want to express finishing a task, terminar is safe and common. Use completar when you mean making something whole, filling missing parts, or finishing all required elements. For formal reports, finalizar or concluir can sound more polished. Pay attention to context: completar often implies that there was something incomplete that is now being made complete.
Pronunciation and Accent
Pronunciation: completan is pronounced /kom.pleˈtan/ in IPA. Break it down into syllables: com-ple-tan. The stress falls on the last syllable tan, because Spanish words that end in a consonant other than n or s are usually stressed on the last syllable; in this case, however, completar is a regular verb and the conjugated form completan keeps the stress on the penultimate syllable of the infinitive root plus the conjugation pattern yielding the /ˈtan/ stress.
Sound tips: The initial com sounds like the English com in comment but with a pure o sound, not a diphthong. The ple is like play but without the y sound. The final tan rhymes with Spanish man but with a clear t sound.
Common mistakes: English speakers sometimes place stress on the wrong syllable, saying com-ple-tán or com-ple-tan with the stress in the middle. Also, watch the t sound: Spanish t is dental and softer than the English t, produced with the tongue touching the upper teeth. Avoid adding an extra vowel at the end; do not say completan-uh.
Native Speaker Nuance and Usage Context
Everyday speech: Native speakers use completan in many everyday situations. For example, teachers might say Ellos completan el examen to report that a group finished their test. Office colleagues use it when reporting progress on tasks: Ellos completan las tareas asignadas.
Formal vs informal: completan is neutral and fits both formal and informal contexts. In casual conversation, people might prefer terminar or acabar, especially in some regions. In formal writing or business communication, completar or finalizar might be used to sound precise.
Regional differences: Some Spanish-speaking regions favor certain synonyms. For example, in some Latin American countries acabar is more common in casual talk for finishing something, while completar remains clear and understood everywhere. Context will guide which verb feels more natural.
Collocations and phrases: Common collocations include completar una tarea, completar un formulario, completar un proyecto, completar una colección. These set phrases help you recognize the verb in different contexts. For instance, completar un formulario is a frequent phrase when dealing with paperwork or online forms.
Politeness and register: When giving instructions, native speakers often use the imperative or present progressive. For example, Completen el formulario, por favor is a polite request to a group. Using completan in statements describes facts: Ellos completan su trabajo a tiempo conveys reliability.
