Practice, nicht practise. Practise wäre üben.

For British English: "practice" is the noun, "practise" is the verb.
In AE I gather the distinction is less important, and "practise" is used for both. Correct me if I am wrong, someone!

Ghol: In AE, both are written "practice"!
BTW: Are you familiar with apt words?

Nancy: Apt words? You mean: words that fit the bill, suit the purpose? To the point, honed? I always try to use 'em.

Ghol: Da kann ich nur sagen, "Boh, eh!"

Nancy: was that the right answer? And if so, what then?

Ghol: Well, drop me an e-mail.
