Related patterns
Similar
ても concedes a single hypothetical or real circumstance with no reference to any other case (雨[あめ]が降[ふ]っても行[い]く); にしても grants a stated case while implicitly treating it as one member of a set to be enumerated (子供[こども]にしても大人[おとな]にしても) — reach for にしても when the concession is about WHICH case among several, not just whether one condition holds.
Lookalikes
One kana apart (に／と) and routinely misread as free variants — としても grants a single hypothetical case ("if it were so", お金[かね]があったとしても), while にしても enumerates real cases side by side (子供[こども]にしても大人[おとな]にしても) — swapping one for the other in a list of real alternatives vs. a lone granted hypothetical reads oddly even though both gloss "even if/granting".
