Pore vs. Pour

When you are studying with great concentration, are you poring over or pouring over the books?
Answer:
poring

Both verbs can be used as phrasal verbs but they have different meanings. Here are a few examples:

When we’re intently studying a subject, nothing is actually pouring (that is, flowing or leaking) onto the object of study; if something did pour onto what you’re poring over, your activity would be far more challenging. The less familiar verb pore is correct.

pour out is a phrasal verb
pour out (something) or pour (something) out:
to freely express (an emotion); to talk freely about (something personal)
  1. I listened while he poured out his anger and frustration.
  2. I’m sorry about pouring out my troubles like this.
  3. She poured out the whole story.
pour out  your heart/soul:

to speak very freely to someone about your private and most deeply felt emotions

  1. He’ll pour his heart out to anyone who will listen.
