What does illumining mean?
Illumining means casting light on something or, more often in figurative English, helping someone understand a subject clearly. The word suggests that an idea, explanation, example, or observation is revealing and intellectually illuminating. When used physically, it refers to light falling on or revealing a person, object, or place; when used figuratively, it describes a piece of writing, discussion, or discovery that makes a complicated subject more accessible. In everyday use, illuminating is more frequent than illumining, but both convey the idea of bringing something into view. The expression is often applied to examples, insights, accounts, and discussions, with a mildly formal or literary tone. It can also refer to actual light, though this usage is less common and often appears in descriptive or poetic writing.
Providing light or making something easier to understand.
"The scholar offered an illuminating account of the ancient text."
The figurative sense—enlightening, clarifying, or revealing—is more common in modern usage than the literal sense of providing light.
To illuminate or clarify; to make something visible or understandable.
"A brief comparison is illumining the difference between the two theories."
This is the present participle form, used in continuous constructions; the more common standalone adjective form is illuminating.
Sometimes the brightest illumination is not physical: a single well-chosen word can light up an entire idea.

Where does illumining come from?
Illumining is the present participle of illuminate, which comes from Latin illum(in)are, meaning “to light up.” That Latin verb is formed from in-, meaning “into” or “upon,” and lumen, the Latin word for light. English later developed both the literal sense of lighting or illuminating and the figurative sense of making a subject clear. Related English words include illumination and luminous.
