Example
The scientist measured the virus in nanometers to understand its size.
Example
That object cannot be seen with our eyes because it's smaller than one nanometer.
Example
How many nanometers are in a millimeter?
Context: "language"
(prefix) used at the beginning of words to mean 'through' or 'across.' This prefix helps show that something is happening all the way from one side to the other.
Example

Example
A monologue doesn’t have 'dia' because it's just one person talking, with no one across from them.
