おばさん

おばさん
noun
aunt; middle-aged woman
1. aunt
One's parent's sister. Can also refer to the wife of one's parent's brother (aunt by marriage).
My aunt is good at cooking.
I stayed at my aunt's house.
I'm going to visit my aunt.
おばさん(はは)(あね)です。
My aunt is my mother's older sister.
I bought a souvenir for my aunt.
2. middle-aged woman, ma'am
Used to address or refer to a middle-aged woman who is not related to you. Similar to 'ma'am' in English, though can sound less formal.
The lady at the vegetable shop is kind.
The lady in the neighborhood greets me every day.
おばさん、これいくらです
Ma'am, how much is this?
The lady at the shop gave me a freebie.
おばさんなったら(なに)したい?
What do you want to do when you become middle-aged?

おばさん has two main uses: addressing a family aunt, and addressing or referring to a middle-aged woman.

KANJI FORMS (for family aunt):

  • 叔母(おば)さん: aunt younger than your parent
  • 伯母(おば)さん: aunt older than your parent

In practice, most people write おばさん in hiragana regardless.

SOUND-ALIKE WARNING:
おばさん (aunt / middle-aged woman) and おばあさん (grandmother / elderly woman) sound very similar. Pronouncing the wrong one can cause offense — be careful with vowel length.

FORMALITY:
When speaking about your own aunt to others, use 叔母(おば)/伯母(おば) (without さん). When referring to someone else's aunt politely, おばさま is more formal.

RELATED:

  • おじさん: uncle / middle-aged man
  • おばあさん: grandmother / elderly woman
