Definition

To diagnose means to identify a disease or problem by examining its signs and causes.

To diagnose is to work out what illness, condition, or problem someone has by analyzing symptoms, tests, or evidence. Doctors diagnose medical conditions, and people also diagnose technical or organizational issues. It often implies a careful process of investigation rather than a quick guess.

Examples

  • After reviewing the scans, the specialist could diagnose the condition with confidence.
  • I couldn’t diagnose the strange noise in my laptop until I removed the back panel and inspected the fan.
  • She asked the team to diagnose why customer complaints had increased so sharply over the last month.
  • They brought in an engineer to diagnose the power failures before restarting the production line.

Common mistake

Learners often confuse diagnose (identify the problem) with treat (deal with the problem) and say “diagnose him” instead of “diagnose him with something” or “diagnose the condition.”
