Descriptive attributes of the name itself — not a confidence measurement, and not an overall quality score. Namewise doesn't approve or disapprove of names.

Pronunciation clarity

Editorial judgement of how consistently this name is pronounced correctly on first read, mapped from an easy/moderate/variable rating to a number. Describes the name — not a measure of evidence confidence.

Spelling simplicity

Calculated directly from the name's spelling: shorter names with fewer irregular letter clusters score higher. A disclosed formula, not an editorial opinion — and not a confidence measurement.

Recorded regional spread

Derived from how many geographies' official statistics record this name. It measures where the name is registered, not how well-known it feels to people living there.

International spread

Derived from the same official statistical coverage, scaled to reflect how widely the name crosses national datasets. Not a measure of how easily it is understood in another language.

Trend stability

Derived from the name's traditional/modern classification and its current popularity trend direction.
