What does the sentence structure ＡでもＢ mean in this song?


The song in question can be found [here](https://youtu.be/eOfaBZ1LohA). For
example:

> いっぽんでもニンジン

While I do know that でも means 'but', I also know that most particles have
multiple meanings.

Since 'but' wouldn't make much sense as a translation here, I am confident
that でも is used here to mean something else. That's what my question is about.

What does the sentence structure ＡでもＢ mean as it is used in the song?




The でも in the song is conditional/hypothetical "even if" (indicating 逆接の仮定条件),
rather than the conjunction (接続詞) でも, "but", which usually comes at the
beginning of a sentence.

The でも here consists of で (the continuative form (連用形) of the copula だ) +
binding particle も.

So 「AでもB（だ/です）」 means "(It's) B, even if it's A."

> １本 **でも** ニンジン _lit._ (It's) ninjin, even if one.  
>  → It's called [ni]{2}njin, even if there's one piece (of carrot).
>
> ２足 **でも** サンダル _lit._ (They're) sandaru, even if two pairs.  
>  → You call them [san]{3}daru, even if you've got two pairs (of sandals).

Examples of this でも:

>   * 雨 **でも** 行きます。 I'll go even if it's rainy.
>   * 難しい仕事 **でも** やります。 I'll do even if it's a difficult task.
>   * ２個100円。３個 **でも** 100円。 Two for 100 yen. It'd still be 100 yen even if
> you bought three.
