Pronunciation

  • Classical: [fiː.liˈaː.lɪs][1]
  • Ecclesiastical: [fi.liˈaː.lis][1]

Forms

fīliālis (neuter fīliāle); third-declension two-termination adjective[1]

Etymology

It is formed from Latin fīlius (“son”) + -ālis.[1][2][3] De Vaan traces fīlius to Proto-Indo-European *dʰ(e)h₁i-l- (“suckling, child”).[4]

Earliest recorded meaning

The earliest examples are in a sermon falsely attributed to Augustine, of filial love towards God, and in Pseudo-Rufinus, of filial fear.[2][3][5]

Semantic evolution

In Christian writers it described the love or fear proper to a son or daughter;[2][6] Honorius Augustodunensis contrasts servile fear with filial fear.[2][6] In medieval canon law it was used of the relation between a mother church and a daughter church.[7][6][8] It also served as a noun for a daughter, from Hugo of Flavigny on,[8] and a Hungarian charter of 1405 has filialibus suis, “her daughters”.[9]

Neo-Latin authors from Petrarch on spoke of filial devotion and filial piety.[10] English took filial from it in the late 14th century.[11]

Timeline
