Setting Clear Requirements
When using 'as long as' for requirements, we establish clear conditions that must be met for something to happen. This differs from pure duration by focusing on necessary conditions rather than time periods. The structure follows: [outcome] + as long as + [requirement].
Expressing Conditions and Promises
'As long as' can express agreements, promises, or commitments that depend on specific conditions being met. This creates a clear cause-effect relationship between the requirement and the outcome.
Examples
