IPA: /ˈlɛtʌp/
KK: /ˈlɛtʌp/
A decrease in speed, strength, or intensity; a pause or break in something that is usually continuous.
After weeks of heavy rain, there was finally a letup in the storm.
Letup → The word 'letup' originates from the phrase 'let up', which means to cease or diminish in intensity. It is a combination of 'let' (from Old English 'lætan', meaning to allow or permit) and 'up' (meaning to a higher position or level). The term describes a reduction in severity or intensity, as in a break from something that was previously ongoing.
Think of 'allowing' something to 'ease up' — that's why letup means a reduction in intensity.
