Concrete and abstract nouns
Names of things that we can perceive with our senses — sight, hearing, touch — are concrete nouns: uy (house), non (bread), daryo, bulbul, qo‘shiq (song). Names of concepts that the senses cannot grasp, only thought, are abstract nouns: baxt (happiness), do‘stlik (friendship), aql (mind), sevinch (joy), go‘zallik (beauty), sabr (patience). Abstract nouns are not usually counted: we do not say “three happinesses”, but we say uchta uy (three houses). Some words can be used in either sense. Most abstract nouns are formed with -lik, -ch, -inch.
“Can you touch it?”: the teacher says a word; children answer “concrete” if it can be seen or touched, “abstract” if not.
