Using 'possible' without 'it is' to sound complete, e.g., 'Possible that we win.', Confusing with 'likely' which indicates probability, not just potential., Overusing in casual conversations where simpler phrases like 'we can' might fit better.	Confused with 'viable' vs 'viability' - remember 'viable' is the adjective., Using 'viable' incorrectly with non-project contexts, like personal opinions., Mixing up 'viable' with 'valid' - 'viable' relates to practicality, 'valid' to correctness.
用法说明	在商业或学术环境中使用'可行的'。避免在随意对话或日常情况下使用。 Use 'feasible' in business or academic contexts. Avoid in casual conversation or everyday situations.	This phrase is used to express potential or ability. It is appropriate in both spoken and written contexts, but can be more formal in academic settings.	在讨论实用且可实现的选项或计划时使用'可行的'。在非常随意的场合避免使用；听起来更专业。 Use 'viable' when discussing options or plans that are practical and achievable.
