しかも and なお both mean "furthermore; in addition; nevertheless" but here they are used together


I was looking up しかも - "furthermore; nevertheless" from this sentence:

> しかも敵との間合いはキープしたままだ。 Nevertheless keep just within range of the enemy

but I am confused by this usage I saw on alc.co.jp

> しかもなお悪いことに worse still

Rikaichan tells me that なお has a very similar meaning to しか yet here they are
used together when I feel that just しかも would suffice.

Could somebody explain this please?




This becomes clearer if you consider the whole sentence. Let's say we have two
facts:

> ドーナツが一個しかない。そのドーナツが腐っている

We can change this to

> ドーナツが一個しかなく、しかもそのドーナツが腐っている

To indicate "in addition to that", or "on top of that".

Separate from this, let's say we wanted to eat lots of donuts. Given the facts
we might say:

> ドーナツが一個しかないのは悪い。そのドーナツが腐っているので、もっと悪い

This can be made more natural by changing it to:

> ドーナツが一個しかなく、なお悪いことにそのドーナツが腐っている

So there are two different meanings here. One is that something happened on
top of another thing, and that there is a bad situation, which became worse.
Combining these, we can say:

> ドーナツが一個しかなく、しかもなお悪いことにそのドーナツが腐っている
