Fluctuation Meaning in English
word
释义
A frequent or sudden change, especially in level, amount, or value over time. Often used to describe movement up and down in prices, temperature, or conditions.
用法与细微差别
'Fluctuation' is formal and common in scientific, financial, or technical contexts. Collocates with 'price', 'temperature', 'market', and 'demand'. It always implies movement up and down—not just a one-way change. Not used for living things (don't say 'fluctuation of people').
