The non-but でも/ても Even if、although

We have studied　も which means 'also'. When added after the て form of a verb or adjective it brings on the meaning of 'even if'. Let's investigate:

冗談を言っても、彼は笑いません。
joudan wo ittemo, kare wa waraimasen.
Even if you tell a joke, he won't laugh.

And an adjective:

冷たくても、食べられます。
tsumetakutemo taberaremasu.
Even if it is cold, I can eat it.

And just stick it after a noun

スーパマンでも、そんなことはできないよ。
su-paman demo　sonna koto wa dekinai yo.
Even Superman can't do that!
