trend
This word captures the sensation of a shifting current. It suggests a collective movement where many individual actions align to create a visible pattern. While a fad is a sudden, short-lived burst of popularity, a trend implies a more sustained trajectory that often signals a deeper change in behavior or taste. In modern digital contexts, the word has evolved from a statistical observation into an active verb. To trend is no longer just to follow a pattern, but to achieve a peak of visibility in the attention economy, often associated with algorithmic amplification and viral speed.
Countable when referring to a specific fashion or style (the latest trends in footwear). Uncountable when referring to the general phenomenon of change (the trend of increasing urbanization).
