Častá chyba:
Learners sometimes use 'fluctuation' when they mean a single change, saying *'a fluctuation in price from $5 to $10'* instead of simply 'a change in price'. 'Fluctuation' is normally used for a series of changes over time. Learners also sometimes say *'fluctuations of the temperature is high'*; the correct structure is 'temperature fluctuations are high' or 'there is a lot of fluctuation in the temperature'.
