GRAMMAR
〜次第だ
depends on
Explanation
NOTE

次第しだいだ means it depends on X — the outcome is determined by the preceding noun.

成功せいこうするかどうかは、あなたの努力どりょく次第しだい
Whether you succeed depends on your effort.
次第だ comes at the end and points back to the noun that decides the result.
NOTE

Use it when you want to say the result is completely decided by a single factor — person, condition, or thing.

NOTE

It attaches directly to a noun — no particle in between. The clause it answers usually ends in かどうかは or .
