Usage of 减 (jiǎn)
The character 减 primarily means "to reduce," "to subtract," or "to decrease." It is commonly used in contexts involving numbers, quantities, or abstract concepts like weight or costs.
Common contexts
- Mathematics and calculations: 减 is used to indicate subtraction, as in 数学题里要先减去这个数 (subtract this number first in the math problem).
- Reducing quantities or amounts: It appears in everyday contexts such as reducing working hours, costs, or weight.
- Health and lifestyle: Often used when talking about losing weight (减肥).
Collocations and patterns
- 减少 (jiǎn shǎo): to reduce, to decrease — a very common compound.
- 减肥 (jiǎn féi): to lose weight.
- 减价 (jiǎn jià): to reduce price, discount.
- 减轻 (jiǎn qīng): to lighten, to alleviate.
Nuances
When using 减, the focus is on the act of making something smaller or less. It is more formal and specific than some synonyms like 降 (jiàng), which often relates to lowering in rank or level. 减 is often paired with measurable quantities.
Common confusion
Avoid confusing 减 with 降, which also means "to lower" but is used more for abstract or hierarchical reductions (like 降级, demotion). 减 is more concrete and numerical.
