IPA: /sʌbˈklɪnɪkəl/
KK: /sʌbˈklɪnɪkəl/
Referring to a condition or disease that does not show obvious symptoms or effects that can be detected by standard medical tests.
The patient was diagnosed with a subclinical infection that did not show any visible symptoms.
Subclinical → It is formed from "sub-" (meaning under or below) and "clinical" (from Greek "klinein", meaning to lean or to bed). The word "subclinical" refers to a condition that exists below the level of clinical detection or diagnosis.
Think of something that exists 'under' ('sub-') the level of 'clinical' observation — that's why subclinical refers to conditions not easily detected.
