Answer:
Freedom of expression is the freedom of citizens to express their beliefs, without prior control by the state. Freedom of expression is not absolute, like most other fundamental rights. For example, hate speech or incitement to violence, mention of obscenities, insults and defamation are punishable under certain circumstances. Freedom of expression is often considered an integral concept in democracies. The freedom to express one's opinion without fear of persecution is explicitly stated in the Universal Declaration of Human Rights.
