Software Design/Use a single term to point to a concept

Checklist questions:

• A single term is used for a concept in variable, function, class names and API documentation?

Why

• Easiness of change (easier to find all places related to the concept that may need to be changed)
• Discoverability (easier to find all places related to the concept in the codebase)
• Apparency of semantics, structuredness, and steepness of learning curve: readers identify the concept quicker
