A strong conjecture about and empathy for another's situation.

“〜sazo〜darou・sazokashi”: Surely 〜, I Imagine (empathetic conjecture)

「さぞ(かし)〜だろう／でしょう」 means “surely 〜, I imagine, it must have been 〜” — expressing a strong conjecture about another's situation or feelings, often with sympathy, empathy. E.g. 「一人で育てて、さぞご苦労されたでしょう」 (raising them alone, it must have been so hard), 「さぞお疲れでしょう」 (you must be tired), 「合格して、さぞお喜びのことでしょう」 (having passed, you must be so happy). It echoes 「〜だろう/でしょう/ことでしょう」, with a solemn, considerate tone. ⚠️ 「さぞかし」 is the emphatic form of さぞ (stronger). ⚠️ さぞ is for empathizing with another, not for blame or factual statement.

🧠 Core nuance: putting yourself in their shoes, surely they must be 〜

The core is a strong conjecture about another's situation/feelings ＋ sympathy, empathy: 「さぞ〜だろう/でしょう」 expresses ‘(putting yourself in their shoes) surely they must be very …' (さぞ大変だっただろう = it must have been so hard, さぞお疲れでしょう = you must be tired), with a considerate, empathetic nuance. It's not a cool objective conjecture, but a conjecture with feeling, thinking of the other person (sympathizing with their hardship, joy, sorrow). ⚠️ It must echo 「〜だろう/でしょう/ことでしょう」 (さぞ〜だろう), expressing conjecture. ⚠️ 「さぞかし」 is the emphatic form of さぞ (stronger: さぞかし驚いたことだろう = they must have been quite surprised). ⚠️ さぞ is for sympathy, empathy (the other's hardship, joy, feelings), ✗ for blame, command, or pure factual statement. A somewhat written, solemn, warm expression.

2. For sympathy, empathy: さぞ is for putting yourself in another's shoes (hardship, joy, sorrow); ✗ blame, command, pure fact.
3. さぞかし is the emphatic form: さぞかし is stronger than さぞ (surely very …).
4. Warm, written: さぞ leans written, solemn, warm, common in condolences, sympathy.
