I'm unsure if the following underlined words are concrete or abstract noun?
  • had a seizure
  • seizure symptoms
  • injuries
  • services
  • the call
  • address
  • treatment
  • the society
  • rewards
  • hours
  • plans
  • support
  • handout
  • scheme
  • perception
Thank you!
What are your opinions first, Ohayo?

An abstract noun refers to states, events, concepts, feelings, qualities, etc., that have no physical existence.
A concrete noun refers to objects and substances, including people and animals, that exist physically.

Following is my answer. Do correct me if I'm wrong.
  • had a seizure abstract
  • seizure symptoms abstract
  • injuries concrete
  • services abstract
  • the call abstract
  • address concrete
  • treatment abstract
  • the society abstract
  • rewards concrete
  • hours abstract
  • plans abstract
  • support abstract
  • handout concrete
  • scheme abstract
  • perception abstract
I think these should perhaps be:
  • the society abstract/concrete-- it depends
  • rewards concrete/abstract-- it depends on what kind of reward
  • plans abstract/concrete-- are they written down?
Many are hard to pin down; use in context may vary the assessment.
