Superposición vs. solapamiento vs. solape
The Spanish words superposición, solapamiento, and solape can all translate to the English word overlap, but they are used in different contexts. The word superposición implies placing something completely or partially over something else, often translating to layering or superimposition. The word solapamiento is the most standard term for a partial intersection of times, ideas, or physical spaces. Finally, solape is a shorter synonym of solapamiento that is especially common in physical, mechanical, and construction contexts.
Superposición
The word superposición conveys the action of placing one element over another. While it functions as overlap, it leans heavily toward the concepts of layering, stacking, or superimposition. It is widely used in scientific, digital, artistic, and geological contexts where objects, waves, or images are placed on top of each other.

Solapamiento
The noun solapamiento is the most common and versatile translation for overlap when describing a partial coincidence. It is routinely used to describe abstract or temporal intersections, such as overlapping schedules, shared responsibilities, redundant concepts, or intersecting data sets.

Solape
The term solape is a shorter, alternative noun that shares the exact same core meaning as solapamiento. However, solape is often preferred in physical, tangible, or technical contexts, such as describing the overlapping edges of construction materials, fabrics, or mechanical parts, though it is still perfectly valid for schedules.

Summary
To choose the correct word, consider the nature of the overlap. Use superposición for layering, stacking, or superimposing objects and images. Choose solapamiento as your general, go-to term for intersecting schedules, concepts, and responsibilities. Opt for solape when you want a shorter term, particularly when dealing with the physical overlapping of materials in construction, engineering, or sewing.
