文法句型

economical + noun (policy/growth/system)

用法筆記

⚠️ This sense overlaps heavily with the adjective 'economic,' which is the standard word for describing matters of the economy. In almost all contexts, use 'economic' instead of 'economical' — for example, 'economic policy,' 'economic growth,' 'economic development.' Using 'economical' in this sense is rare and may be considered nonstandard. Reserve 'economical' for senses 1–3 (not wasteful, avoiding the truth, profitable).

常見錯誤

The country faces serious economical problems.
The country faces serious economic problems.
💡Use 'economic' for broad economy-related matters; 'economical' in this sense is rarely used and may sound wrong to native speakers.
