Answer:
A concrete noun is a noun (such as chicken or egg) that names a material or tangible object or phenomenon—something recognizable through the senses. Contrast with an abstract noun.
(i.e. grass, student, building)
Things that come out of the abstract noun may be touched and seen, but the abstract noun itself cannot. The most common examples of abstract nouns are time and feelings. They are real, but they cannot be seen or felt.
(i.e. feelings: honesty, trust, lust)
