I've been reading a book in Japanese in order to learn new kanji, words, etc.,
but I've come across something I can't seem to translate. The sentence is as
follows.

> 老人にも若者にも、富豪にも乞食にも、学者にも無頼漢にも、イヤ女にさえも、全くその人になり切ってしまうことができるといいます。

I'm familiar with all the words and grammar within the sentence, and, based on
context clues, I think I have a rough understanding of what this sentence
means. But I'm a bit uncertain of what なり切ってしまう actually means, as I don't
think we're talking about the verb 'to cut'. It's my understanding that 切る has
a good handful of other meanings, so I thought it must be one of those which
I'm unfamiliar with.

And, to give a little bit of context in case that helps, this is from Edogawa
Ranpo's novel「怪人二十面相」and the sentence above is describing the thief's ability
to disguise himself.

question
grammar meaning words
What does なり切ってしまう mean?
>
> 「富豪{ふごう}にも乞食{こじき}にも、学者{がくしゃ}にも無頼漢{ぶらいかん}にも、イヤ女にさえも、全{まった}くその人になり切{き}ってしまうことができるといいます。」

「なり切る」 means " **to really get into the role** ", " **to act a role
perfectly** ", etc.

「なる」 in this expression means " ** _to become ~~_** " in the sense of " ** _to
play the role of ~~_** "

「切る」 here means " **to do something completely or to the end** ".

> "From tycoon to beggar, scholar to scoundrel, and even a woman -- (this man)
> is said to be capable of acting any kind of role just perfectly."
