The Tono-Pen is a handheld device thatâs shaped like a large marker. It provides a digital readout of eye pressure. Your doctor can use it to touch your eye and measure pressure. Though useful in many cases, the Tono-Pen is considered less accurate than the Goldmann tonometer in people with normal corneas.
The English language has two types: British English and American English. Other variations such as Oxford English, Standard English, or other variants are mere adaptations of the two types (especially for consistency or reference use, e.g., in media or publication). British English.
Linguists, however, do make a distinction between the two based on the concept of mutual intelligibility. Two languages where speakers can understand each other are considered dialects of the same language, whereas two languages where the speakers cannot understand each other are, indeed, separate languages.This often isn't black and white, since understand can be a hard criterion to pin down.here is also the notion of a dialect continuum, wherein languages A and B are mutually intelligible and languages B and C are mutually intelligible, but A and C are not.
