An old native Japanese word. まま means 'step-' (as in step-parent) and () means child. The prefix まま also appears in 継父(ままちち) (stepfather) and 継母(ままはは) (stepmother).

ETYMOLOGY:
The prefix まま is of ancient origin and is thought to derive from a word meaning 'not real' or 'substitute.' It predates Chinese-derived words for step-relations.

COMMON COLLOCATIONS:

  • 継子(ままこ)(あつか)い: being treated unfairly, like a stepchild
  • 継子(ままこ)いじめ: bullying of a stepchild
  • 継子(ままこ)(そだ)てる: to raise a stepchild

SIMILAR WORDS:

  • ()(): a child from a previous relationship — neutral, commonly used in modern contexts
  • 養子(ようし): adopted child — a child formally adopted, not necessarily a stepchild
  • 実子(じっし): biological child — one's own child by birth

NOTE:
In modern usage, ()() is more commonly used than 継子(ままこ) to refer to stepchildren without negative connotation. 継子(ままこ) can carry undertones of the old fairy-tale motif of the mistreated stepchild, making it somewhat loaded.
