diagnosis
DYE-uhg-NOH-sis
/ˌdaɪ.əɡˈnoʊ.sɪs/
The identification of the nature of an illness or other problem by examination of the symptoms.
Involves a systematic process of gathering information (symptoms, tests) and using medical knowledge to determine the specific disease or condition.
The story behind the word. The word 'diagnosis' comes from the Greek 'diagnōsis,' which literally means 'a discerning' or 'distinguishing.' It's formed from 'dia-' meaning 'through' or 'apart' and 'gnōsis' meaning 'knowledge' or 'acquaintance.' So, a diagnosis is essentially gaining knowledge 'through' careful examination and distinguishing between different possibilities to arrive at a clear understanding of a condition.
