Well, I learnt a new word today: ‘toponym’.
The dictionary defines it thus: noun: a place name, especially one derived from a topographical feature. Its origins are from the Greek topos ‘place’ + -onym ‘name’.
Wikipedia defines toponymy as the study of place names (toponyms), their origins, meanings, use, and typology.
The word can refer to a non-specific feature, such as lover’s leap (or lovers’ leap or lovers leap – for the apostrophe-minded amongst you), hence it is anywhere that lovers may leap from. It also refers to a name that describes the place (I suppose lovers leap does that too if you know where it is); Northumberland is the ancient territory (land) of those living north of the River Humber.
Are you getting the drift of it now?
What other toponyms can you come up with?
