Ways to tell them apart:

etymology
  • The word prognosis shares the prefix pro- which can remind you of project or predict—both related to forecasting the future.
  • Diagnosis starts with dia- which can remind you of diagram or detailed, relating to identifying present conditions.
  • Think of prognosis as involving prospects, which is similar sounding and thinking about future outcomes.
  • Diagnosis is often the first step before prognosis, as you need to know what the condition is before predicting its trajectory.
  • Prognosis can change over time as the condition unfolds, but the diagnosis remains as the initial determination or uncovering of what the issue is.
