Linguistics Spotlight enables you to bookmark and/or share any content you read on the app.
When on the app page for an individual item of content -e.g. an article abstract, a blog post, a YouTube video, etc. – look for the Bookmark icon and/or Forwarding Arrow icon top-right.
If you bookmark an item, it will be added to your Reading List (accessible through the main menu).
When sharing an item, you will be given options to share via email, Facebook and Twitter.
