ㄹ/을 리가 없다

Overview

The grammatical pattern ㄹ/을 리가 없다 is used to express a strong conviction that a particular situation, event, or fact cannot possibly be true or happen. It conveys a sense of disbelief or certainty that something is logically impossible or goes against common sense. Essentially, it means 'there is no way that...' or 'it's impossible that...'

Usage

This expression is employed when the speaker wants to emphatically deny the possibility of something. It's often used in situations where a statement or a perceived event seems utterly illogical or contrary to known facts. The '리' in '리가 없다' refers to 'reason' or 'grounds,' so '리가 없다' literally means 'there are no grounds/reasons' for something to be true. It adds a strong nuance of impossibility based on reasoning or strong conviction, rather than just a simple denial. It can be used to express surprise, doubt, or even indignation when faced with an unbelievable claim or situation.

Conjugation Rules

The conjugation depends on whether the stem ends in a consonant or a vowel, and whether it's a verb, adjective, or noun.

1. Verbs and Adjectives:

• If the stem ends in a vowel or ㄹ (for verbs/adjectives ending in ㄹ, ㄹ is dropped and ㄹ is added again): -ㄹ 리가 없다
  • 가다 (to go) -> 갈 리가 없다
  • 만들다 (to make) -> 만들 리가 없다
• If the stem ends in a consonant (except ㄹ): -을 리가 없다
  • 먹다 (to eat) -> 먹을 리가 없다
  • 좋다 (to be good) -> 좋을 리가 없다

2. Nouns:

• For nouns, -일 리가 없다 is used.
  • 학생 (student) -> 학생일 리가 없다
  • 의사 (doctor) -> 의사일 리가 없다

Important Note: The tense is expressed in the preceding verb/adjective stem, or by adding -았/었을 리가 없다 for past tense, or -겠을 리가 없다 for future/conjecture, though the latter is less common.

• Past tense: 갔을 리가 없다 (There's no way he went)
• Present tense: 갈 리가 없다 (There's no way he goes/will go)

Knowledge Plus

• ㄹ/을 리가 없다 is a stronger expression of impossibility than simply using '안 되다' or '못 하다'. It implies a logical or factual impossibility rather than just an inability or prohibition.
• It is often followed by an explanation or a rhetorical question expressing disbelief.
• Compare with -을 수 없다 (cannot, unable to). While -을 수 없다 indicates an inability or lack of possibility, -ㄹ/을 리가 없다 expresses a strong conviction that something is simply not true or cannot happen based on reasoning or evidence. For example, '나는 수영할 수 없다' (I cannot swim - inability) vs. '그가 거짓말을 할 리가 없다' (There's no way he would lie - strong disbelief).
• The expression can also be used with the past tense marker -았/었- (e.g., -았/었을 리가 없다) to express impossibility about a past event. For example, '그가 벌써 도착했을 리가 없어.' (There's no way he's already arrived.)
