[Grammar pattern] V(ます) + まして…: Meaning and Example Sentences

A grammar pattern used to connect verbs or clauses, conveying reasons for the speaker's action in a polite manner.
"まして" is the polite form of the conjunctive particle "て", which is used in the て-form of verbs.
In conversation, when the speaker believes that the listener can infer the clause after "まして", the clause is often omitted and the sentence ends with "まして".
