Selective Serotonin Reuptake Inhibitor

Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption into the presynaptic cell. They have varying degrees of selectivity for the other monoamine transporters, with pure SSRIs having a strong affinity for the serotonin transporter.

Affirmative Action

Affirmative action, also known as positive action or positive discrimination (British English), involves sets of policies and practices within a government or organization seeking to include particular groups that were historically discriminated against in areas in which such groups are underrepresented, mistreated or suffer from lack of public support—such as education and employment.

Collective Noun

In linguistics, a collective noun is a word referring to a collection of things taken as a whole. Most collective nouns in everyday speech are not specific to one kind of thing. For example, the collective noun "group" can be applied to people ("a group of people"), dogs ("a group of dogs"), or objects ("a group of stones").
