the young married woman a wedding brings into a family: the bride beside her husband, or a son's wife in his parents' household
Greek names this woman with one word, and which English word fits depends on who is looking at her. Put her beside the man she is marrying and she is the bride, the woman at the center of the wedding, the counterpart of the bridegroom (νυμφίος). Put her inside her husband's family home and the same word means the son's wife, what English calls the daughter-in-law, the one Jesus pictures set against her mother-in-law (πενθερά) in a household pulled apart.
That double use is not a quirk of Greek. It matches the Hebrew word it usually stands in for (כַּלָּה), and it matches how families actually lived. A son did not move out to start a separate home, so from her wedding day the young wife was at once a bride to him and the new woman of his parents' house. English has to pick one label or the other, but one word held both.
In the New Testament the wedding side dominates, and it quickly reaches past ordinary weddings. Only the song over fallen Babylon uses the word for everyday married life, where the voices of groom and bride go silent in a ruined city. Elsewhere it carries a picture: John the Baptist says the bride belongs to the bridegroom and that he is only the friend standing by, glad to hear his voice, and Revelation closes by showing the holy city coming down from God dressed like a bride, naming her the wife (γυνή) of the Lamb, and letting her voice join the Spirit's invitation to come.
