Nuances and Usage Notes
单 can be used as an adjective or in compound nouns. When used in 单独, it stresses independence or solitude. In 订单, it refers to a formal order or request, which is a common business term.
Avoid confusing 单 with similar characters like 单纯 (simple, pure) where 单 is part of a compound with a different meaning. 单 alone focuses on singularity or individuality.
