depending on; so~
Expresses that something depends on a condition or situation, similar to 'depending on' in English.
Use 次第で to say that the outcome or situation changes based on something else. It's like saying 'it depends on X'. The noun before it is the deciding factor. For example, 結果は君の努力次第だ means 'The result depends on your effort.' You can also use it with verbs in the form 〜かどうか次第で, meaning 'depending on whether...' as in 行くかどうか次第で (depending on whether we go). This pattern is common in both speech and writing, but it sounds a bit formal when used in casual conversation. It's neutral in politeness, so you can use it in most situations, but in very casual talk you might hear 次第 by itself or 次第でね.
