Kerb
The word kerb corresponds to the edge of a raised path nearest to the road and which also separates it from the road.
Origin
The word, which has been around since the 1660s, is a spelling variant of curb that has turned out to become the preferred British English spelling for certain specialised senses, like “edging of stone or pavement”
Prevalence
The word has grown in usage over the past two centuries and even though there was a dip late in the last century, it has again risen to match its previous bests.
Usage
Providing ramped kerbs at crossing places makes it easier for those with wheelchairs and prams.
