the pointed top of a mountain

tatters of fog clung to the peak of the mountain

a projecting pointed part or shape

whisk two egg whites to stiff peaks

the point of highest activity, quality, or achievement

he was at his peak as a cricketer

package holiday sales hit a peak of around 12 million

reach a highest point, either of a specified value or at a specified time

the disease peaked in summer

decline in health and spirits; waste away

she sat all day, peaking and pining, at the fire-side
