Here's a small lesson on the family and immediate members. (I will elaborate on this at another time :3)

• father: otoosan (oh-toh*long o*-sah-n) = someone else’s father
  chichi (chee-chee) = 'my' father (only used when speaking of your own)

• mother: okaasan (oh-kah*long a*-sah-n) = someone else’s mother
  haha (hah-hah) = 'my' mother (once again-only used for one's own parent

• grandfather: ojiisan (oh-jee*long e*-sah-n) ; also a term for elderly men-not necessarily an 'actual grandpa' (sort of like the English term 'gramps', just not considered rude)
• grandmother: obaasan (oh-bah*long a*-sah-n) ; also can be term for elderly women- just like ojiisan
• older brother: oniisan (oh-nee*long e*-sah-n) = someone else’s big brother
  ani (ah-nee) = ‘my’ older brother

• older sister: oneesan (oh-neh*long eh*-sah-n) = someone else’s older sister
  ane (ah-neh) = ‘my’ older sister

• younger brother: otootosan (oh-toh*long o*-toh-sah-n) = someone else’s younger brother*
• younger sister: imootosan (ee-moh*long o*-toh-sah-n) = someone else’s younger sister*

*When speaking of your own younger siblings, remove the ‘san’ on the end. This is a title of respect and it is considered wrong, rude, and conceited to place honor on your own family.

This was a brief lesson on family titles. Thanks for joing me today, I hope you find this helpful. As always, if you have any questions, just pm me or comment them in!! :3
