This is the 15167th most frequent Russian word.
получив
"Having received."
In this sentence, 'получив' forms a gerund (verbal adverb) indicating an action ('having received') that precedes the main action ('immediately replied').
Получив письмо, он сразу ответил.
Having received the letter, he immediately replied.
Here, 'получив' again functions as a gerund bridging the feeling ('felt joy') resulting from receiving good news.
Она почувствовала радость, получив хорошие новости.
She felt joy upon receiving good news.
In this example, 'получив' explains the prior action ('received education') that sets the context for the subsequent action ('returned').
