长足

• 拼音: cháng zú
• 汉字拆解: 长 = simplified 長; 足 = pictograph of a foot and leg

含义

Significant; substantial; great (of progress or development). Describes remarkable advancement or improvement.

Almost exclusively used as an adjectival modifier in the fixed phrase 取得长足进步/进展/发展/改善 (to make significant progress/advances/development/improvement). The metaphor is of a 'long stride' — a meaningful leap forward. NOT used independently to describe a person or thing, and not interchangeable with 很多 or 巨大 outside of progress-related contexts. Register: formal, written.
