When I was talking about the power of smell on the radio, Speth, a Welsh speaker from Manchester, got in touch to say that in Welsh you can hear a smell as well as smell it. At first this sounded charming, if far-fetched. But the more I thought about it, the more sense it made.

I can feel the shop man’s grip as he lifts me into the saddle. And I can hear him saying to my grandad: “Blimey, he’s a lump, isn’t he?” Ever sensitive about my weight, that was a sour note. But I’ll let it pass, because all I can feel, then and now, is the general joy.
