けれども

けれども is a conjunction used to connect two clauses, expressing contrast, contradiction, or concession. It translates to "but," "however," or "although" in English.

けれども is the most formal member of a family of related conjunctions. From most formal to most casual, they are:

• けれども – formal; used in writing, speeches, and polite conversation
• けれど – semi-formal; polite but slightly softer
• けど – casual; common in everyday conversation

All three share the same meaning and grammatical function. The choice depends on the level of formality.

Expressing contrast

けれども connects two clauses where the second clause presents something unexpected or contradictory given the first.

Structure

けれども attaches to the end of a clause in its plain or polite form:

• Verb + けれども: いきます行きますけれども
• い-adjective + けれども: ちいさい小さいけれども
• な-adjective + だ + けれども: しずか静かだけれども
• Noun + だ + けれども: がくせい学生だけれども

In polite speech, the clause before けれども often uses the ます/です form:

Softening or introducing a topic

Like けど, けれども can appear at the end of a sentence without a second clause, leaving the conclusion implied. This softens the statement or introduces a topic politely.

This trailing usage is very common in polite requests and business Japanese.
