Have you ever seen an IEngine in the wild?
TL;DR: Don't prefix or suffix your classes
Problems
Readability
Bijection Fault
Implementative Names
Solutions
Remove prefixes and suffixes
Name your objects after what they do
Context
Some languages have cultural conventions related to data types, Abstract classes, or Interfaces.
These names load our models with cognitive translations hard to follow.
We must KISS.
Sample Code
Wrong
public interface IEngine
{
void Start();
}
public class ACar
{
}
public class ImplCar
{
}
public class CarImpl
{
}
Right
public interface Engine
{
void Start();
}
public class Vehicle
{
}
public class Car
{
}
Exceptions
In C# it's a common practice to put "I" in the name of an interface because without it, you can't tell whether it is an interface or a class.
This is a language smell.

Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems.
