- Light / light up — make something physically brighter
- Brighten — add light or make something appear more cheerful
- Enlighten — give someone knowledge or understanding
- Clarify — make an idea easier to understand
- Explain — make something understandable through information
- Reveal — make something previously hidden or unknown known
- Highlight — draw special attention to something

The key is to choose a synonym based on physical light, knowledge, explanation, discovery, or emphasis.
What Does Illuminate Mean?
The verb illuminate has two closely connected meanings.
First, it means to provide light or make something visible. For example:
Lanterns illuminated the garden after sunset.
Second, it can mean to make an idea, subject, or situation clearer:
The example illuminated the main problem.
This second meaning is metaphorical. Instead of physically adding light, you are adding understanding.
That distinction is important because not every synonym works in every sentence.
For example, you can say:
The candles illuminated the room.
But replacing illuminated with explained would completely change the meaning.

Examples:

8. Reveal
