What does spikier mean?
Spikier is the comparative form of the adjective spiky. Its most literal meaning is having more spikes or sharp points than something else: a plant may become spikier as its seed heads develop, or a person's hair may be described as spikier after being brushed upward. The word also has a less physical figurative use for something that is more irregular, unstable, or characterized by sudden increases and decreases. A graph might become spikier because a series of values rises and falls sharply, while market observers may describe prices as increasingly spikier. In such contexts, “spiky” suggests abrupt variation rather than a smooth, gradual trend. Spikier is commonly used in both everyday and technical English, although formal financial or statistical writing may prefer terms such as volatile, irregular, or sharply fluctuating.
Having more sharp points or projections than another thing; more pointed in appearance.
"The new design gives the building a spikier silhouette."
Used literally of plants, hair, structures, and other things with pointed projections.
More marked by sharp fluctuations, sudden rises, or irregular changes.
"Demand became spikier late in the quarter."
Common in contexts involving graphs, prices, measurements, and other changing numerical data.
A spiky trend can describe anything that suddenly shoots upward, from a graph of daily temperatures to the pace of a volatile market.
