The pattern for inclusion could follow the example of the following set of four lists. 
 ::*Wikipedia:Vital articles/Level/1 (10 articles) 
 ::*Wikipedia:Vital articles/Level/2 (100 articles) 
 ::*Wikipedia:Vital articles (1000 articles) 
 ::*Wikipedia:Vital articles/Expanded (potentially 10,000 articles) 
 ::Thus, we might have the following set of four lists. 
 ::*List of languages by name (level 1) (10 languages) 
 ::*List of languages by name (level 2) (100 languages) 
 ::*List of languages by name (level 3) (1000 languages) 
 ::*List of languages by name (level 4) (potentially 10,000 languages and dialects)
