One-touch look-up of words in foreign language book

Hello. I was thinking about buying a Kobo Aura reader on which to read French novels because the majority of modern French language books published in ebook format are in epub with the Adobe DRM system.

I am still learning French and it is only practical for me to read a book in French if one-touch word translation is available. That is that I can hold my finger down on an unknown word for a second and a definition pops up on the screen, which I can then dismiss with a single extra touch, to continue reading.

I am happy to buy a French-English e-dictionary to go on the Kobo if that's needed to enable that capability, as I would expect.

Note I do not expect it to be able to translate multi-word passages, like Google translate does. That is much more complex, and unnecessary for me.

Can anybody tell me if one-touch word translation like this is available on a Kobo? If not on a Kobo, are there other Adobe DRM-compatible readers on which it is available?

They would need to be readers, not tablets, as I don't like extended reading from a non e-ink screen. Plus I like to read out in the garden, and it's too hard to read an LCD/LED screen in sunlight.

Thank you very much.
