pronoun
A polite, honorific second-person pronoun. Used to address someone respectfully, often in service or formal contexts. More deferential than そちら alone.
そちら様のご住所をお聞きしてもよろしいでしょうか。
May I ask for your address?
そちら様はどちらからいらっしゃいましたか。
Where are you from, if I may ask?
そちら is a polite but less formal 'you' or 'that direction'. そちら様 adds the honorific suffix 様, making it more respectful and suitable for addressing customers or strangers.
あなた is a common second-person pronoun, but can sound blunt or intimate depending on context. そちら様 is more honorific and often used in service situations.
Combination of そちら (that direction, you) and the honorific suffix 様 (さま). The exact historical derivation is uncertain, but the form is a conventional polite address.
