-로 인하다

Due to, Because of

Level 4Sounds Like ro inhada

-로 인하다 means "due to [Noun]" or "because of [Noun]". It's a formal way to state a cause for a resulting situation.

How It Works

-로 인하다 is a formal grammar pattern used to express a clear cause-and-effect relationship. It is primarily found in written language, such as news articles, official reports, and academic papers, as well as in formal presentations or announcements.

Formation:
It attaches directly to a noun.

  • Nouns ending in a vowel or the consonant ㄹ + -로 인하다
    (e.g., 사고 → 사고로 인하다, 실수 → 실수로 인하다)
  • Nouns ending in a consonant (except ㄹ) + -으로 인하다
    (e.g., 태풍 → 태풍으로 인하다, 사건 → 사건으로 인하다)

Common Usage Forms:
While -로 인하다 is the base form, you will most often encounter it in these conjugated forms:
1. -로/으로 인해(서): This adverbial form connects the cause to the result clause. It means "due to..." or "as a result of...".
(e.g., 폭설로 인해 길이 막혔다. - The road was blocked due to the heavy snow.)
2. -로/으로 인한: This adjectival form modifies a noun that follows. It means "caused by..." or "resulting from...".
(e.g., 부주의로 인한 사고 - an accident caused by carelessness)

Nuances:
While it can be used for neutral situations, -로 인하다 is frequently used to explain the cause of negative events or problems. It is much more formal than common reason-giving patterns like -아/어서 or -기 때문에.

Common Mistakes

  • Using -로 인하다 in casual, everyday conversation.

    Different Meaning친구야, 교통체증으로 인해서 늦었어.
    Better친구야, 차가 막혀서 늦었어.

    -로 인하다 is too formal for talking with friends. In casual situations, use simpler expressions like -아/어서 or -기 때문에. '차가 막혀서' is a much more natural way to say 'because of traffic'.

  • Attaching -로 인하다 directly to a verb stem instead of a noun.

    Not Quite비가 많이 오다로 인해 경기가 취소되었어요.
    Better폭우로 인해 경기가 취소되었어요.

    -로 인하다 must follow a noun. To use a verb as the reason, you must first change it into a noun form using a nominalizer like -는 것 or -기 (e.g., 비가 많이 오는 것으로 인해). However, it's often more natural to use a single noun that summarizes the action, like '폭우' (heavy rain).
