What Is a Creole Language?

A creole language, or simply a creole, is a stable natural language that has developed from a pidgin, i.e., a simplified version of a language. Creoles differ from pidgins because creoles have been nativized by children as their primary language. As a result, they have features of natural languages that are normally missing from pidgins, which are not anyone's first language.

The Etymology of the Word 'Creole'

The English term creole comes from French créole, which is cognate with the Spanish term criollo and Portuguese crioulo. All descend from the verb criar ('to breed' or 'to raise'), which comes from the Latin creare ('to produce, create').^[15] The specific sense of the term was coined in the 16th and 17th centuries...

Formal Complaint Letter

Hospital Managing Director
Carretera Torrebonica, Terrassa, Barcelona

15 March 2014

Dear Director,

I am writing to formally complain about the treatment I received during my recent four-day stay at your hospital.

First, I would like to express my dissatisfaction with the nursing staff. They were consistently unfriendly and appeared unapproachable. When I required urgent assistance, there were significant delays. Furthermore, the care provided lacked gentleness and compassion; tasks were performed hastily and poorly.

Secondly, I am dissatisfied with the hospital's facilities and conditions:

• Bed Quality: The bed in my room was broken and produced a loud, persistent noise that prevented me from sleeping.
• Utilities: There was

The Cold War: A Summary

Key Social Topics in Spain

Right to Education

When we talk about the right education, we refer to the right to a school education for children. In Spain, education is compulsory until sixteen years of age. In underdeveloped countries, a great majority of children do not have this right, and most organizations work for this cause. From my point of view, all people should have this right and be able to make use of it. Rich countries, for example France or the USA, should provide financial support for this cause.

Young People and Family Bonds

In Spain, families and friends are important and very close. A tradition is to gather the entire family on Sundays for lunch and spend the day together. From my experience, my family is very small but we are... Continue reading "Spanish Social Issues: Education, Family, and Consumerism" »

The Fundamental Right to Education

We know the importance of education for the healthy development of a person and society. This progress is possible thanks to education. In Spain, education is compulsory until the age of 16. However, in other countries, many children do not go to school. To understand the importance of the right to education, we shall look at what happens in less developed countries where this right is not assured.

Challenges in Underdeveloped Nations

In underdeveloped countries such as Bangladesh, for instance, in the 12-16 age group, only 26% of girls and boys go to school. What are they doing if they don't go to school? Unfortunately, they must perform the following activities to survive:

• Working in factories, mines, or markets,
