Discuss the rules for forming the future perfect tense in Korean and provide examples.

In Korean, the future perfect tense is used to express an action or event that will be completed or finished at a specific point in the future before another future action or event occurs. It indicates an action that will have been done by a certain time in the future. The future perfect tense is formed by combining the verb stem with the auxiliary verb "겠" (get) and attaching the appropriate verb ending based on the sentence structure. Let's delve into the rules for forming the future perfect tense in Korean and provide examples:

1. For action verbs ending in a vowel:

* Remove the verb stem's vowel ending.
* Add "을" (eul) if the previous final consonant is a batchim, or "ㄹ" (l) if it is a vowel.
* Attach "겠" (get) to indicate the future perfect tense.
* Attach the appropriate verb ending based on the sentence structure.Example:
Verb: 가다 (gada) - to go
Future Perfect Tense: 갈 겠다 (kal getda) - will have gone

* Sentence Ending Example:
내일까지 일을 다 마칠 겠어요. (Naeilkaji ireul da machil gesseoyo.)
Translation: I will have finished my work by tomorrow.
2. For action verbs ending in a consonant:

* Remove the verb stem's final consonant.
* Attach "을" (eul) if the previous final consonant is a batchim, or "ㄹ" (l) if it is a vowel.
* Attach "겠" (get) to indicate the future perfect tense.
* Attach the appropriate verb ending based on the sentence structure.Example:
Verb: 먹다 (meokda) - to eat
Future Perfect Tense: 먹을 겠다 (meogeul getda) - will have eaten

* Sentence Ending Example:
저녁까지 저는 식사를 다 먹을 겁니다. (Jeonyeokkkaji jeoneun siksa-reul da meogeul geopnida.)
Translation: I will have finished eating by dinner time.
3. For descriptive verbs:

* Remove the verb stem's final "다" (da).
* Attach "을" (eul) if the previous final consonant is a batchim, or "ㄹ" (l) if it is a vowel.
* Attach "겠" (get) to indicate the future perfect tense.
* Attach the appropriate verb ending based on the sentence structure.Example:
Verb: 예쁘다 (yeppeuda) - to be beautiful
Future Perfect Tense: 예쁠 겠다 (yeppul getda) - will have been beautiful

* Sentence Ending Example:
휴가가 끝날 때쯤에는 꽃들이 다 시들어 있을 겁니다. (Hyugaga kkeutnal ttaejjeumeun kkotdeuri da sideureo isseul geopnida.)
Translation: By the end of the vacation, the flowers will have withered.
