Obstáculo vs. impedimento vs. escollo
The Spanish words obstáculo, impedimento, and escollo all translate to obstacle or hindrance in English, but they carry distinct nuances. While obstáculo is the most general term, impedimento suggests a more definitive block, and escollo refers to a specific, often hidden, difficulty.
Obstáculo
B1Obstáculo is the most common and general term for an obstacle. It refers to any physical object or figurative difficulty that stands in the way and must be overcome, removed, or navigated around.

Impedimento
B2An impedimento is a condition, rule, or circumstance that prevents or makes an action impossible. It is a stronger, more definitive block than an obstáculo and is often related to legal, bureaucratic, or physical limitations.

Escollo
C1Escollo refers to a specific, often unforeseen difficulty or stumbling block within a process, negotiation, or journey. It carries the metaphorical sense of a hidden reef that can shipwreck a plan. It is more specific than an obstáculo.

Summary
In summary, use obstáculo for any general obstacle, physical or figurative. Use impedimento for a more definitive barrier that prevents an action, often due to rules or personal conditions. Use escollo for a specific, tricky difficulty or snag within a larger process like a negotiation or project.
