Is the place of "instead" correct in below sentence B?
I usually use the "instead" at the last of the sentence If I want to use the other choice as shown in sentence A.
Thanks.A. If your notebook supports wifi, then you can use your notebook for accessing the internet. Otherwise, you need to use this PC to access the internet instead.
B. If your notebook supports wifi, then you can use your notebook for accessing the internet. Otherwise, you need to use this PC instead to access the internet.
"A" & "B" both work, but B is the better sentence. "A" requires the reader to apply some logic and eliminate "...the Internet" as being the alternative that "instead" refers to. That doesn't make your sentence wrong, but it is a bad habit; sooner or later you will write something that will be ambiguous, and the reader will be unable to ascertain your intended meaning.
Get in the habit of using the form of "B"; it's smarter, clearer writing.
