Definition
  1. Noun:
    • A male sibling related through the remarriage of a parent: A stepbrother is a brother who is not biologically related, but is the son of one's stepparent from a previous relationship. This relationship is created when one's parent marries someone who already has a son.
Usage
  • The term "stepbrother" is used to describe a specific family relationship formed by marriage, not by blood.
  • It is a compound noun formed from "step-" (indicating a relationship resulting from a parent's remarriage) and "brother".
  • It is a neutral, factual term for this family role.
Examples
  • Noun:
    • After my father remarried, I gained a stepbrother named David.
    • My stepbrother and I share no biological parents, but we grew up in the same house.
    • She introduced him as her stepbrother at the family gathering.
Advanced Usage
  • "Half-brother" vs. "Stepbrother": A crucial distinction. A half-brother shares one biological parent with you. A stepbrother shares no biological parents; the connection is solely through the marriage of one of your parents to one of his parents.
    • My half-brother and I have the same mother. My stepbrother is my stepfather's son from his first marriage.
Variants and Related Words
  • Stepsister (n): A female sibling related through the remarriage of a parent.
    • My stepsister and I became close friends.
  • Stepparent (n): A parent who is married to one's biological parent but is not one's biological parent.
  • Stepfamily (n): A family where at least one parent has children from a previous relationship.
Synonyms
  • No direct single-word synonyms. The concept is specific. Descriptive phrases include "brother by marriage" or "non-biological brother from a parent's marriage."
Related Phrases
  • "My brother from another mother": A casual, often affectionate slang phrase that can sometimes be used humorously for a stepbrother or a very close friend, though it is not technically accurate. It emphasizes a strong bond despite a lack of biological connection.
