I find that it takes me a while to get used to reading two words written as one, usually as part of a business name. I saw women with items of clothing or with bags marked "lululemon", a seller of women's athletic wear, and it took me a long time to read the name as "Lulu Lemon", as I gather it should be read. For some months I was sounding it inwardly as a double iamb: luLUleMON. Fortunately, I never had to discuss it with anyone.
Then there is the restaurant "levelone" on 17th and S Sts. NW. After about dozenth time I walked by, I read "Level One". Yet I still can't shake the feeling it should rhyme with "provolone".
