Difference between とあれば、にあって、とあって


Can someone please explain the difference between

  * **とあれば**
  * **にあって**
  * **とあって**

I've read the explanation from my 新完全マスター book but I'm afraid I don't fully
understand the difference in nuance between these grammatical patterns.

Thanks




> 「～～ **と** あれば」= " ** _if_** it is for ~~". Think of it as an emphatic form
> of 「なら」.

「よし[子]{こ}のためとあれば、[死]{し}んでもかまわない。」 = "I would not mind dying it it were for
Yoshiko."

You can insert 「もし」 at the beginning of the sentence if you want to.

Occasionally, you will encounter the literary form 「～～とあ **ら** ば」. The form
"-- **a** ba", instead of "-- **e** ba" is heavily used in set phrases such as
「急{いそ}がば回{まわ}れ」 ("Slow and steady wins the race.").

> 「～～ **に** あって」= "during ~~", "in the condition of ~~" Think of it as an
> emphatic form of 「に」.

「この[非常時]{ひじょうじ}にあっても、キミ子は[冷静]{れいせい}だった。」= "Even during this emergency, Kimiko
was calm."

> 「～～ **と** あって」= "because of ~~", "due to the fact that ~~", etc. It
> expresses the specialness of the occasion.

「５[年]{ねん}に[一度]{いちど}のお[祭]{まつ}りとあって、[誰]{だれ}もが[興奮]{こうふん}していた。」 = "Because it was
a once-in-every-five-years festival, everyone was excited."
