optimum or optimal?
Is there a difference between optimum and optimal?
As adjectives, they have the same meaning: best; most favourable; most conducive to a good result
They both come from the Latin optimus, meaning “best”.
Look at these examples:
- What is the optimum/optimal childbearing age?
- We need to find the optimal/optimum solution.
- In our case, the optimum/optimal investment would produce a modest return at no risk.
Optimum can also be a noun, while optimal has two derivatives:
- optimally (adverb)
- optimality (noun)
