も particle after an adverb


I know that も particle can be used in place of は、が、を. And it means "in
addition", "also".

What function does it have in this adverb "不運にも"? Should we treat it as a
separate word here?

explains the expression `不運にも` on p. 382 as _a sentence adverb_ (文副詞).

Some adjectives like `不運な`, `幸運な`, `意外な`, `皮肉な`, `勇敢な`, `卑怯な`, etc. can take
`も` after their conjuntive form to add some _evaluation, criticism, or
commentary_ of speaker to the whole sentence.

For example, the sentense

> 意外にも、彼は集会に現れた。 (Surprisingly, he showed up to the assembly.)

expresses _indirectly_ that the speaker did not expect that he would show up.
This _unexpectedness_ is not the main topic of this sentence, but a kind of
commentary from the speaker's point of view.

Here is another example:

> その警察官は勇敢にもギャングから人質を救出した。 (The policeman bravely rescued the hostages from
> the gang.)
