Fluctuation Meaning in English
word
Definition
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.
Usage & Nuances
'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').
