If he had known, he would have done it in Korean 🇰🇷

Sentence info.

"그가 알고 있다면, 그는 그것을 했을 것입니다." is built in two parts: a conditional clause and a main clause.

1. Conditional Clause – "그가 알고 있다면"
• Structure: Subject (그가 = he) + verb phrase (알고 있다 = to know/to be aware) + conditional suffix (‐다면, meaning “if …”).
• Meaning: It sets up the condition “if he knows” or “if he were aware.”
• Tip: Remember that adding “‐면” (or “‐다면” for extra emphasis) to a verb or adjective creates an “if” clause in Korean.
• Romanization: "Geuga algo itdamyeon"

2. Main Clause – "그는 그것을 했을 것입니다"
• Structure: Topic/subject (그는 = as for him) + object (그것을 = it) + verb (했을 것입니다 = would have done).
• Explanation: "했을 것입니다" uses the past form of “하다” (to do) combined with “것” plus the ending “‐입니다” (or “‐습니다” in formal speech) to express a counterfactual or hypothetical result.
• Tip: To express “would have done” in Korean, form the past form of the verb, attach “‐을/‐ㄹ 것” and finish with an appropriate ending like “입니다/습니다.”
• Romanization: "Geuneun geugeoseul haesseul geosimnida"

Alternate Expressions:
• "만약 그가 알았다면, 그는 그것을 했을 텐데."
 – "만약" means “if” or “supposing that,” and "알았다면" uses the simple past form of “know” with the conditional suffix. "했을 텐데" is a common colloquial way to express "would have done."
 – Romanization: "Manyak geuga aratdamyeon, geuneun geugeoseul haesseul tende."

• "그가 알았더라면, 그는 그것을 했을 것이다."
 – "알았더라면" is another variant of the conditional form using an alternative past conditional ending, and "했을 것이다" conveys the hypothetical result.
 – Romanization: "Geuga aratdeoramyeon, geuneun geugeoseul haesseul geosida."

These constructions help you express hypothetical or counterfactual situations in Korean by clearly tying a condition to its consequence.
