Distinguir vs. divisar vs. vislumbrar
The Spanish verbs distinguir, divisar, and vislumbrar can all be translated to English as to make out or to discern. However, they are used in different contexts depending on how the subject is perceiving the object. The main differences lie in whether the focus is on clarity and separation, spotting something far away in the distance, or catching a weak, partial, or metaphorical glimpse.
Distinguir
The verb distinguir focuses on clarity, identification, and differentiation. It means to perceive something clearly enough to identify its features, to separate it from its background, or to tell two similar things apart. It can be used for visual, auditory, and conceptual perception.

(I can make out the red house among the trees.)

Divisar
The verb divisar strongly emphasizes distance and geography. It means to spot, sight, or make out something that is far away, often after scanning the horizon or looking from a high vantage point.

(From the top of the mountain we managed to make out the immense ocean.)

Vislumbrar
The verb vislumbrar implies a weak, incomplete, or fleeting perception. It means to catch a glimpse of something or to dimly make it out, usually because of poor lighting, physical obstacles, or rapid movement. It is also frequently used in a metaphorical sense to mean suspecting, foreseeing, or beginning to understand an abstract concept.

Summary
To summarize, choose distinguir when you need to emphasize clarity, identifying details, or telling things apart. Use divisar when you are spotting or sighting an object far away in the distance. Finally, opt for vislumbrar when you only get a faint, incomplete physical glimpse of something, or when you are metaphorically beginning to perceive an idea or future event.
