Grammar Patterns

filial + noun (duty, devotion, respect, piety)

Usage Note

Almost always attributive, sitting before an abstract noun (duty, love, devotion, piety, respect, responsibility). Rarely used after 'be' on its own — say 'a filial son' rather than 'he is filial'.

Common Mistakes

He is very filial to his parents.
He is a very filial son.
'filial' normally modifies a noun, not the subject directly.
She showed filial to her grandmother.
She showed filial devotion to her grandmother.

Grammar Patterns

filial + relationship noun (bond, role, generation)

Usage Note

Distinguish from sense 1 by reference: this sense names the structural role of being a child (bond, generation, position), while sense 1 names the moral behaviour expected within that role (duty, respect, piety). The biology meaning is the clearest example of this structural sense.

Common Mistakes

My filial daughter is five years old.
My young daughter is five years old.
native speakers do not call children themselves 'filial'; the word describes the role or bond, not the person's age.

Sense: adjective/1

All four words describe a person who fulfils obligations to others, but only 'filial' is reserved for the bond between a child and a parent or older relative. 'Filial' is a formal, often literary word — you meet it in phrases like 'filial duty' and 'filial piety', and it carries echoes of traditional family ethics. 'Dutiful' is broader: a dutiful soldier, a dutiful employee, a dutiful neighbour — duty can be owed to anyone or any role. 'Devoted' shifts the focus from obligation to feeling — a devoted son loves his parents, while a filial son honours them, with or without warmth. 'Respectful' is the everyday word and works in any direction, including a teacher being respectful to students. Compare: 'He is a filial son who visits his parents every Sunday' (cultural duty) vs 'He is a devoted son who calls his mother every day' (emotional bond).

Etymology

LatinLate LatinOld FrenchMiddle EnglishEnglish

From Late Latin 'filialis', built on Latin 'filius' (son) and 'filia' (daughter). The same Latin root gave English 'affiliate' (to take in as a son or member) and 'filiation' (the legal relationship between parent and child). The word entered late Middle English through Old French, and from the 1300s onward it was used in formal religious and moral writing to describe how children should behave toward their parents.
