Usage notes
* Not to be confused with principle.
This is generally not used in the comparative or superlative in formal writing, as the meaning is already superlative. However, one may occasionally see, e.g., more principal meaning more likely to be principal or more nearly principal. There are similar issues with unique.
The confused may care to remember that 'The principal alphabetic principle places A before E' as a reminder of the relative spelling.
