Abstract - concrete noun
From Hull AWE
- Concrete nouns refer to things you can actually experience directly through your senses - e.g. a brick, a window, a smell, a song, or a taste.
- Abstract nouns are the things that only exist in the mind, such as religion, an idea, and an argument. (Note that an abstract noun can be either a common noun - e.g. religion - or a proper noun - e.g. Buddhism, Christianity or Islam.)
