adverbial N3 common casualpolitewritten

確かに — certainly / indeed

確かに・たしかに

Meaning

certainly / indeed / true — acknowledging something as a fact, often before a 'but'

確たしかに彼かれの言いう通とおりだ。

He's certainly right.

Very often sets up a concession — 確たしかに〜が／けど ('true, ..., but ...') — granting the other side's point before pushing back.

確たしかにこの店みせは高たかいが、味あじは最高さいこうだ。

True, this place is expensive, but the food is the best.

「彼かれは努力家どりょくかだね。」「確たしかに。」

"He's a hard worker, isn't he." "Indeed."

Without に, 確たしか means 'if I remember correctly' (確たしか3時じだった = 'it was 3 o'clock, I think') — a hedged, uncertain meaning, almost the reverse of 確かに.

Jengo shows 確かに the way you actually meet it: inside real Japanese sentences, so it sticks instead of staying an abstract rule.
