Language is the road map of a culture. It tells you where its people come from and where they are going. -Rita Mae Brown 

A language is a method of communication. Most human languages use patterns of sound or gesture for symbols which enable communication with others. There are thousands of human languages, and these seem to share certain properties, even though every shared property has exceptions.

Every human knows at least one language, spoken or written. Linguistics is the art of language, including the sounds, words, and grammar rules. Words in languages are limited, but sentences are infinite; it is this creative aspect in human communication that sets it apart from those in animals.

The phrase of social justice is often related to the action of developing a just society by challenging injustice and appreciating diversity. Social justice is generally equated with the notion of equality or equal opportunity in society. Although equality is undeniably part of social justice, the phrase of "equal opportunity" and other similar phrases such as "personal responsibility" have been used to diminish the prospective for realizing social justice by justifying enormous inequalities in modern society (Berry, 2005).

Essentially, social justice occurs when people share a common humanity and therefore have a right to justifiable treatment, support for their human rights and a fair division of community resources. In conditions of social justice, people must not be discriminated against their well-being, controlled or prejudiced on their basis of gender, religion, age, race, belief, disability, location, social class, socioeconomic circumstances, or other characteristic of background and group membership.

Global challenges must be administered in a way that distributes the costs and burden fairly in accordance with basic principles of fairness and social justice. Those who suffer or who benefit least deserve assistance from those who benefit the most.

The United Nations (UN) International Human Solidarity Day is annually held on the 20th of December to celebrate unity in diversity. International Human Solidarity Day highlights the importance of acting in common cause on behalf of society’s most vulnerable people. It aims to remind people on the importance of solidarity in working towards eradication of poverty. On this Day, governments are also reminded of their commitments to international agreements on the need for human solidarity as an initiative to fight against poverty. People are encouraged to debate on ways to promote solidarity and find innovative methods to help in eradicating poverty.

Let us make migration work for the benefit of migrants and countries alike. We owe this to the millions of migrants who, through their courage, vitality and dreams, help make our societies more prosperous, resilient and diverse. Ban Ki-moon Secretary, General of the United Nations

Immigrants are often perceived as criminals, economic burdens, security threats and even risks to public health. Negative views about immigrants shape government policy and action on immigration around the world, often resulting in limited or no protection for immigrant workers and their families.

Each year, the United Nations invites UN Member States and intergovernmental and non-governmental organizations to observe International Migrants Day through the dissemination of information on the human rights and fundamental freedoms of migrants, as well as through the sharing of experiences and the design of actions to ensure their protection.
