Verhindern vs. vorbeugen vs. vermeiden vs. unterbinden vs. verhüten
The English verb to prevent can be translated into several different German words depending on the context, the timing of the intervention, and the nature of what is being stopped. Understanding the subtle nuances between the words verhindern, vorbeugen, vermeiden, unterbinden, and verhüten is essential for choosing the correct term for situations ranging from medical precautions to stopping a crime.
Verhindern
The word verhindern means to actively stop a specific event, action, or state from happening. It implies a direct intervention to block an outcome and is the most common general translation for preventing concrete events like accidents, crimes, or plans.

(The police were able to prevent the bank robbery at the last second.)

The word vorbeugen is used when taking precautionary measures beforehand to ensure something negative does not arise. It is very frequently used in medical contexts to talk about preventing diseases or injuries, and it usually requires the dative case.

The word vermeiden is closest in meaning to the English word to avoid, but it is often used where English speakers might say to prevent by steering clear of something. It is used when you change your own behavior or choices to ensure a negative situation, mistake, or conflict does not occur.

Unterbinden
The word unterbinden means to nip something in the bud or forcefully put a stop to an action that is already developing or ongoing. It carries an authoritative tone and is often used by figures of authority to prohibit behaviors, discussions, or illegal practices.

Summary
To choose the right German word for preventing something, look at the nature of the action.
