This is to make watching subbed anime more clear. I was always confused with the different titles, by that i mean, chan, sama, kun. So here is little thing that i thought would help.
San (さん) is the most common honorific and is a title of respect it s usually rendered as a common courtesy title like “Mr.” or “Ms.”
Kun (君) is an informal honorific primarily used towards males, It is used by persons of senior status in addressing those of junior status
Chan (ちゃん) is a diminutive suffix. It is an informal version of san used to address children and female family members. It may also be used towards animals, lovers, intimate friends
Sensei (先生) is used to refer to or address teachers, practitioners of a profession such as doctors and lawyers, politicians, and other authority figures.
Sama (様) is the formal version of san. This honorific is used primarily in addressing persons much higher in rank than oneself and in commercial and business settings to address and refer to customers.
Oneesama (お姉様) is a term which literally translates as respected elder sister, but can be used (especially by admirers) to refer to any young female.
