～ことは～ (certainly true, but)

• Reading: ことは
• Romaji: koto wa
• Formation: Verb (plain) + ことは + Verb (same, plain) + が/けど～

Meaning

A construction that repeats the same verb or adjective before and after ことは to concede that something is certainly true, while implying a reservation or qualification in the following clause.

The pattern Verb/Adj + ことは + same Verb/Adj is a concessive structure. The speaker acknowledges a fact but then introduces a contrasting clause with が or けど that qualifies it. For example, 食べることは食べた means 'I did eat, certainly, but...' — implying something like 'but not much' or 'but it wasn't good.' This structure gives a nuanced, hedging tone. The repeated element can be a verb, い-adjective, or な-adjective. The first occurrence sets up the concession, and the repetition after ことは reinforces the acknowledgment before the contrast. It is commonly used in spoken Japanese when someone wants to give a qualified yes.

Examples

1. 読むことは読んだが、内容はよく分からなかった。 I did read it, but I didn't really understand the content.
2. 高いことは高いけど、品質はとてもいい。 It is expensive, certainly, but the quality is very good.
3. 行くことは行きますが、少し遅れるかもしれません。 I will go, but I might be a little late.

Origin & History

This concessive construction uses こと to nominalize the predicate, with は marking it as the topic of concession. The repetition of the predicate creates an emphatic acknowledgment before introducing a contrasting point.
