crunchily, with a rough crunch
The sound or sensation of cutting, chopping, or biting into something with a coarse, satisfying crunch.
Related onomatopoeia
- サクサク: lighter, crisper crunch (thin cookies, pastry); also means "smoothly" for work
- ザクザク: heavier, coarser crunch (thick cuts, gravel, snow)
The voiced ザ vs unvoiced サ reflects the weight of the sound — ザクザク implies something rougher and heavier than サクサク.
