The barrier uh - What is trade barrier? definition and meaning.

Imitators take less risk because they will start with an innovator's product and take a more effective approach. Examples are IBM with its PC against Apple Computer , Compaq with its cheaper PC's against IBM, and Dell with its still-cheaper clones against Compaq.

The identity of er and erm depends on pronouncing them like a native in your head, something we don’t have to do with other words ( chuffed reads as British even if our internal pronunciation is American, and we can accept that Harry Potter will be pronounced differently by an English person even if we don’t actually pronounce it that way internally when we read). This fact, which on the surface seems so obvious, can escape even the most astute readers. Lynne Murphy of the blog Separated by a Common Language  is a linguist who had been living in the UK for years when she finally realized the truth about er and erm . She was watching TV and noticed that the captions for American shows with American actors speaking with American accents used er and erm for uh and um . They were different ways of writing the same sounds. I completely identified with her reaction to this discovery: “Before any of you complain that I should not have been allowed to have a doctorate in Linguistics if it took me this long to figure out something this basic, let me tell you: I've thought the same thing myself. I think the technical term for this is:  Duh! ”
