SEO question - Will this be considered Plagiarism?

Hey guys,
I'm working on a Q/A platform which is scheduled to launch by the end of this April. I'm kinda stuck at something and I need some advice.

The image above shows what the typical category page on my platform looks like. For example, each question has a minimum of 3 tags and once the question is posted, that question is added on the main page of those tags (which I like to call Categories). Now, the thing is that I and my team have to manually add in the image and a short description for each category or else it would look something like this



Now the problem is that there will probably be tens of thousands of category pages and writing a unique description for each category is an impossible task. So, is it possible to just copy a sentence from wikipedia? I've no problem citing the source (along with a no-follow link to wikipedia "if required")

Can this hurt me in the long term?

Another important thing that I would like to point out is that these descriptions will also be added in the meta description section of my website's category pages.

What are your thoughts?

You can copy from Wikipedia, but I highly recommend you to make small changes and improvements on the text so It will not look like a obvious copy. Usually you can increment the content using a video, or audio, or anything else that can make your content more valuable than others.

Bump........

Well the same principle with most thing, take from source, modify it, than make it better and unique.

Guys, that didn't help.

My question is, is it okay to copy "Just a sentence" from any website and add a link to the original source (no-follow)

Here's an example:



@BassTrackerBoats I would appreciate your thoughts on this
