Language is dynamic.
Both the grammar and vocabulary of a language alter over time reflecting social, technical, scientific, and cultural phenomena. These changes are particularly true regarding English because of its position as a world language incorporating influences from the whole world. It is especially true today because electronic communication has increased the rate and the amount of communication in English.
An example of changing vocabulary can be found in the world of development. During the 60s we talked about “undeveloped” countries. This expression was quickly
replaced with “underdeveloped” which hinted at a potential that had not yet been realised. The next word that came into fashion was “developing” which sees development as a continuum and is therefore not as
categorical as the previous expressions. During the 70s and 80s other terms began to be used such as “Third World” and “The South” each with its own special connotation.
Whereas these words with the root “develop” illustrate how a concept can evolve, there are other words and expressions that join the special vocabulary of
development. They reflect the attitude that is the prevailing attitude of the time. Sometimes the words are used with a special meaning in the development context. These words become a kind of shorthand for people
communicating about development issues. However, there is the risk of words losing their meanings. Make sure that you understand the meanings of the words from the special development vocabulary when you use
them. This unit is designed to help you.
