Question

Are the words 'profession', 'job,' 'trip,' and 'appearance' concrete or abstract nouns?

Answer 1

They are abstract nouns because they don't state directly what they stand for but rather a vague meaning left to individual interpretation. Concrete nouns would be blatantly specific in their meaning with little room for individual interpretation of their meaning.

Answer 2

I believe the words profession, job, trip, and appearance are abstract nouns :)
