Being a lion, as any celebrity will tell an interviewer, is a tiresome business. Nobody likes to be gawped at. It's embarrassing. Walter Scott, a literary lion, said of the London celebrity party circuit in 1809:
If I encounter men of the world, men of business, odd or striking characters of professional excellence in any department, I am in my element, for they cannot lionize me without my returning the compliment and learning something from them.
He invented the word and the word stuck, and that's why Banksy has been lionised. It's all the fault of Henry I and Walter Scott.
It only remains for me to tell you that Lionel means little lion and that Singh means lion, so in the unlikely event of somebody being called Lionel Singh I would be ridiculously pleased. Oh, and dandelions are lions' teeth. Oh, and it's a symbol of Saint Jerome.
The paw little thing
P.S. There seems to be no consistency in English spelling between lionise and lionize, I have servilely followed the dictionary.
