What's the difference between あって vs ありまして?


I was taught that the て form of the verb ある is あって, but I sometimes see the
word ありまして acting in the same way. What's the difference and when would you
use one or the other?




「ありまして」is just a really polite form of 「あって」.

In the standard polite sentence, only the final verb is put into the polite
-ます form, while the rest are in the regular dictionary forms:

> 朝ご飯を食べてシャワーを浴びました。

While often overkill, it is possible to put the other connecting verbs into
the -ます form as well. The resulting「まして」form has the same function as the
regular connective -て form, just adding extra politeness- which is why it is
common in keigo sentences.

Also, although this isn't really a problem with ありまして, one thing you should be
aware of is that you cannot use the -まして in a request with ください.

> × 私の作った料理を食べてみましてください  
>  ○ 私の作った料理を食べてみてください
