Defining the Infinitive in Korean: 기본형

The infinitive, or 기본형 (gibonhyeong), is the most basic form of a Korean verb or adjective. It is the primary, unaltered form of a verb, allowing it to be conjugated and combined with other grammar points. In Korean, verbs and adjectives are morphologically similar, so both types of words can have infinitives.

Conjugations and the Korean Infinitive

Unlike English, where the infinitive is typically preceded by “to” (e.g., to read, to swim), the Korean infinitive presents a direct verb or adjective form without any additional markers. Korean follows an agglutinative language structure, meaning words are conjugated through various morphemes, called 용언 활용 (yongeon hwal’yong), indicating tense, politeness levels, and various grammatical relationships.

Usage of Infinitive in Korean Grammar

The infinitive in Korean grammar holds a multifaceted role, as it serves as the foundation for constructing myriad expressions and phrases. The following outlines key scenarios where the Korean infinitive comes into play.

1. Infinitive Conjugation

Conjugating verbs and adjectives is pivotal in Korean, as it is essential for constructing grammatically accurate and coherent sentences. By removing the final 다 (da) from the infinitive verb or adjective, it can then be conjugated with various verb endings, helping it harmonize within sentences and convey multiple nuances such as tense and politeness.

2. Dictionary Form

When searching for a Korean verb or adjective in a dictionary or an electronic translator, the infinitive form is generally used. This is because the infinitive form provides the most coherent, unaltered structure of the word, making it easily recognizable and locatable.

3. Embedded Clauses

In Korean sentences, the infinitive usually appears in embedded clauses, though subject to conjugation, based on the context. For instance, it may manifest as a gerund form or a future tense conjugated form, allowing finer details and more complex meanings to be relayed within a sentence.

Exploring Examples of the Infinitive in Korean

To better comprehend the functions and usage of infinitives in Korean, let’s analyze a few examples:

• Infinitive verb: 먹다 (eat)
• Conjugated verb: 먹어요 (eat – polite form)
• Infinitive adjective: 기쁘다 (be happy)
• Conjugated adjective: 기뻐요 (be happy – polite form)

Notice how the infinitive forms (먹다, 기쁘다) provide the basis for conjugation, yielding various structures and expressions, such as the polite forms (먹어요, 기뻐요).

Conclusion: The Centrality of the Infinitive in Korean Grammar

In summary, a thorough understanding of the infinitive is invaluable to learners of the Korean language. The infinitive, as the foundation of verbs and adjectives, paves the way for complex conjugations, embedded clauses, and serves as a handy starting point in dictionary searches. When embarking on the journey to mastering Korean grammar, a strong grasp of infinitives is undeniably essential and rewarding.
