In simple terms, it means that they or you-all fulfilled, carried out, or reached something in the past.
Basic definition: they fulfilled / they carried out / they turned (age) / you all fulfilled.

Synonyms, Antonyms, and Word Usage Differences
Synonyms: realizar, completar, terminar, obedecer (depending on context). These words can overlap with cumplieron but have different nuances. Realizar and completar focus on finishing tasks. Terminar means to end something. Obedecer means to obey a rule or person, similar to cumplir when the meaning is to follow rules.
Antonyms: incumplir, fallar, abandonar. Incumplir is the direct opposite and means to fail to fulfill or to break a promise. Fallar means to fail or make a mistake. Abandonar means to abandon or give up.
How to choose the correct word: Use cumplieron when you mean that someone completed or fulfilled an obligation, promise, rule, or milestone in the past. If you want to emphasize finishing a specific task, completar or terminar may be appropriate. If the action fails or was not done, use incumplieron (the negative past plural form of incumplir) or fallaron.
Pronunciation and Accent
Pronunciation guidance: cumplieron is pronounced approximately koo-mplee-EH-ron in English-friendly syllables. In IPA: /kumˈpljeɾon/.
Stress: The stress falls on the penultimate syllable -ple- (kum-PLEE-ron). There is no written accent mark because the word follows Spanish stress rules for words ending in a consonant other than n or s; the natural stress is on the penultimate syllable.
Common pronunciation mistakes: Some English speakers may overemphasize the o at the end or change the ll sound. The ll in cumplir is pronounced as a palatal lateral or as a y sound in many dialects, so cumplieron sounds like kum-plee-yon in many regions. Also avoid turning the r into an English r; the Spanish r is tapped, similar to a soft d sound between vowels.
Native Speaker Nuance and Usage Context
Everyday use: Native speakers use cumplieron in many everyday contexts. Common situations include reporting that people completed tasks, kept promises, followed rules, or celebrated anniversaries. For example, a teacher might say Los estudiantes cumplieron con la actividad to mean the students did the activity as assigned.
Formal vs informal: cumplieron is neutral and works in both formal and informal speech. It appears in written reports, news, casual conversations, and formal speeches. The tone and surrounding vocabulary determine the level of formality, not the verb form itself.
Regional differences: The meaning of cumplieron stays the same across Spanish-speaking countries. Pronunciation may vary: in Argentina or parts of Uruguay, the ll sound might sound like [ʒ] or [ʃ], so cumplieron may sound slightly different. However, the grammar and usage are consistent.
Common collocations: cumplir con (to fulfill obligations or meet standards) is the most common phrase. For instance, cumplieron con las normas means they followed the rules. Another common use is cumplir años (to have a birthday), as in cumplieron diez años for they turned ten years old.
Conclusion
cumplieron is a practical verb form that English speakers should learn early because it frequently appears when talking about finished actions, fulfilled promises, followed rules, and celebrated milestones. It is the simple past plural of cumplir and conveys completion. Pronounce it /kumˈpljeɾon/ and remember the stress on the -ple- syllable. Use cumplieron with con when describing meeting obligations or standards, and with años when talking about birthdays or anniversaries. Practicing example sentences and noticing the phrase cumplir con in real conversations will help you recognize and use cumplieron naturally. With regular use, this verb form will become a reliable part of your Spanish toolkit for talking about things people did in the past.
