They would have completed the homework in Korean 🇰🇷

Sentence info.

Breakdown of the Sentence:
• 작업 (jag-eob) – Means “work” or “task.”
• 을 (eul) – Object marker that follows “작업” to indicate what is being acted upon.
• 완료했을 (wallyohaesseul) – A combination of the verb 완료하다 (wallyohada, “to complete”) conjugated in its past form (완료했다, “completed”) plus the future or conditional marker -(으)ㄹ, forming “would have completed.”
• 것입니다 (geosimnida) – Means “it will be” or “it is,” used here to indicate a deduction or assumption in a formal and polite style.

Tips for Remembering the Structure:
• Recognize that Korean often omits the subject when it is understood from context; in this case, the subject “they” is implicit.
• Note the use of the object marker 을 after 작업 to clearly denote what the verb is acting upon.
• The form 완료했을 것입니다 combines past action with a modal expression for probability or supposition.
• In formal speech, ending with -입니다 (imnida) is a useful structure for polite declarations.
