The term "mentally ill" refers to a condition or disorder that affects a person's thinking, mood, behavior, or overall mental functioning. It encompasses a wide range of mental health issues, including anxiety disorders, depression, schizophrenia, and bipolar disorder. Individuals who are classified as mentally ill may experience difficulties in daily life, social interactions, and managing emotions effectively.
The phrase "mentally ill" is derived from the combination of "mental," which comes from the Latin word "mentalis," meaning "of the mind," and "ill," which originates from the Old English word "iell," meaning "unwell" or "sick." Together, they describe a state of unwellness affecting one's mental faculties.
