• SynonymおばあさんNeutralPoliter than 「婆さん」 for a grandmother or an elderly woman; 「婆さん」 is casual and can sound disrespectful.

• Synonym老女ろうじょWrittenA written word for an elderly woman; can also mean a senior lady-in-waiting; not for everyday address.
• SynonymおばあちゃんNeutralMeans grandma or an old lady with a warm, affectionate feel; common in everyday speech.
• AntonymじいさんNeutralThe male counterpart of 「婆さん」: an old man or grandfather; spouses may also call each other 「爺さん」.

For grandmother, 「おばあさん」/「おばあちゃん」 are politer and 「婆さん」 is casual — fine between spouses, but risky with strangers. Use 「祖母」 for neutral reference. 「婆ちゃん」 is affectionate slang; 「老婆」「老婦」「老女」 are written words for old women.
