    確か: certain or sure. The Japanese adjectival noun '確か (たしか)' is used to express certainty or sureness about something. It can be used to confirm information or to indicate that something is reliable or accurate. For example: I'm sure he will come「彼は確かに来るでしょう」(かれはたしかにくるでしょう).

It can also be used to recall something from memory, often with a sense of uncertainty, as in 'I think it was last year, but I'm not sure「確か去年だったと思うけど、確かじゃない」(たしかきょねんだったとおもうけど、たしかじゃない)'. The word can be used in both affirmative and negative contexts, and it often carries a nuance of seeking confirmation or reassurance.
