Is 'concert' a concrete noun or an abstract noun?

Answer 1

Yes, the noun 'concert' is an abstract noun as a word for agreement, accordance, or harmony; a word for a concept.

The noun 'concert' is a concrete noun as a word for a musical performance; a word for a physical thing.

Answer 2

Concrete nouns are words for things that can beexperienced by one or more of the five senses; it can be seen, heard, smelled, tasted, or touched.

Abstract nouns are words for things that can't beexperienced by any of the five senses; they are words for things that we know, understand, believe, or feel emotionally.

Examples
concrete: abstract

• apple: attitude
• block: behavior
• carrot: care
• door: democracy
• egg: ego
• frog: fear
• grass: greed
• ham: hope
• ice: ignorance
• jar: joy
• knee: knowledge
• log: love
• mouse: memory
• notebook: need
• onion: opinion
• pie: pity
• quilt: quest
• rose: right
• stone: secret
• turtle: truth
• umbrella: urge
• vase: value
• water: wish
• yellow: year
• zircon: zeal

There are some nouns that can go either way depending on use. For example, there's the physical heart that you can feel beating in your chest and the heart of the matter or a broken heart.

Then there are the tricky ones, the ones that you have to think about. For example, the abstract noun anger; you can see the angry face, you can hear the angry words, you can see the person twitching with anger, but those are faces and words, the anger is what the person is feeling inside.

Even more tricky abstract nouns are such words like oxygen and carbon dioxide, you can't see them, hear them, or know that you're touching them, but they can be detected and measured with instruments; oxygen and carbon dioxide are physical and they are concrete nouns.

There are some nouns that even the experts can't agree on the designation, and nouns that I can't understand why they're designated as concrete or abstract.

Some teachers of English use a simpler method of determining if the noun is an abstract noun. They tell the student to draw a picture of the word; if you can't draw it, it must be an abstract noun. That doesn't help with the tricky nouns but it is a place to start.
