acute
uh-KYOOT
/əˈkjuːt/

Describes conditions that peak quickly and require immediate attention, distinct from long-term chronic issues.
The story behind the word. From Latin 'acutus', past participle of 'acuere' (to sharpen), related to 'acus' (needle). Early physicians used it to describe fever spikes or sharp, sudden symptoms that struck like a needle poke.
