彼は他人をすぐに責めるきらいがある。 meaning: He tends to blame others quickly.

The sentence follows a typical Japanese sentence structure, Subject-Object-Verb (SOV), although the subject can sometimes be implied. ⚫︎ The sentence is composed of: ⚫︎ Subject: 彼(kare - he) ⚫︎ Topic Marker: は(wa) ⚫︎ Object (implied): 他人を(tanin o - others) ⚫︎ Adverb: すぐに(sugu ni - quickly) ⚫︎ Verb: 責める(semeru - to blame) ⚫︎ Fixed Expression: きらいがある(kirai ga aru - tends to/has a tendency to)

This is a crucial grammar point for N1. ⚫︎ きらいがある(kirai ga aru) is a fixed expression indicating a "tendency," "inclination," or "likeliness" to do something undesirable or negative. ⚫︎ It expresses the speaker's observation or judgment about a person's habits or behaviors. ⚫︎ It is used with the plain form of a verb. ⚫︎ Structure: Verb (plain form) + きらいがある ⚫︎ Example: 彼は遅刻するきらいがある。(kare wa chikoku suru kirai ga aru - He tends to be late.) ⚫︎ Note: This expression suggests something negative or unwanted. ⚫︎ Other similar expressions with more nuance are: ～傾向がある(keikou ga aru - tends to), ～がちだ(gachida - tends to), ～やすい(yasui - easy to do something, often with a negative connotation).

The verb 責める(semeru - to blame) is a る-verb (ichidan verb). ⚫︎ る-verbs are easy to conjugate. ⚫︎ The base form is 責め(seme). ⚫︎ The plain form is 責める(semeru). ⚫︎ The present/future affirmative is 責める(semeru). ⚫︎ The present/future negative is 責めない(semenai). ⚫︎ The past affirmative is 責めた(semeta). ⚫︎ The past negative is 責めなかった(semenakatta). ⚫︎ In this sentence, it is used in its plain form 責める before the fixed expression きらいがある. ⚫︎ The dictionary form/plain form is used with きらいがある. ⚫︎ Example: 彼は嘘をつくきらいがある。(kare wa uso o tsuku kirai ga aru - He tends to tell lies.)

The sentence employs two important particles. ⚫︎ を(o) is a direct object marker. ⚫︎ It marks the noun that is directly affected by the verb. ⚫︎ In this case, 他人を(tanin o - others) is the direct object of the verb 責める(semeru - to blame), so it's marked with を. ⚫︎ In this sentence, there is no に(ni). ⚫︎ に(ni) can mark the indirect object. ⚫︎ に can also indicate the location or time.

すぐに(sugu ni - quickly) is an adverb. ⚫︎ Adverbs modify verbs, adjectives, or other adverbs. ⚫︎ It describes how the action of the verb 責める(semeru - to blame) is performed. ⚫︎ すぐに means "immediately" or "quickly." ⚫︎ It adds information about the manner in which someone blames others. ⚫︎ Adverbs often come before the verb they modify. ⚫︎ Example: 彼はすぐに食べ始めた。(kare wa sugu ni tabe hajimeta - He immediately started eating.)
