transmissible

The word transmissible describes something capable of being passed on from one person or thing to another. While often associated with diseases – like saying a virus is transmissible through airborne droplets – its meaning extends far beyond health and medicine.

Anything that can be transferred, conveyed, or spread can be considered transmissible. This can include diseases, genetic traits passed from parents to children, or information that moves from one person to another. Cultural knowledge and customs can also be described this way when they are passed through generations.

In a scientific context, transmissibility refers specifically to the ease with which an infectious agent spreads. A highly transmissible disease requires fewer contacts to infect someone compared to one that is less transmissible. However, in broader usage, it simply means capable of being passed along.

Think about a family recipe, a traditional song, or a practical skill. These can all be transmissible when they are taught and passed from one generation to the next. In the same way, certain facts, habits, or ways of doing things can move through a group over time.

So, whether we're talking about germs, genes, gossip, or good ideas, transmissible highlights the ability of something to move and be shared between individuals or across time.
