続ける

1. Origins, structure, and basic meaning

• Structure: 続ける (つづける) is a transitive verb for keeping an action going. The examples use progressive continuation and dictionary form under negated necessity.
• Basic usage: Daily walks continue despite rain; when tired, there is no need to force work onward.

2. Common pitfalls and similar expressions

• Habit maintained and work that need not continue
  • Objects are 散歩を and 作業を. The second negates necessity, not merely the continuation event itself.
