in the near future
"the doctor will soon be here"
"the book will appear shortly"
"she will arrive presently"
"we should have news before long"
In a short or brief time or manner; quickly.
"She finished her homework shortly before dinner was served."
In plain English: Shortly means very soon, happening just after now but not right this second.
"She will arrive shortly after the meeting ends."
Usage: Use shortly to mean very soon in the future, such as when telling someone an event will happen immediately after this moment. Do not confuse it with briefly, which describes something lasting only a small amount of time rather than occurring near now.
The word shortly comes from the Middle English term schortly, which was formed by adding -ly to the adjective for "brief." It entered Old English with the meaning of happening in a brief time or very soon, much like its modern usage.
