fly

Compared meaning: to move through the air, to fly (verb).

比较义项：飞、飞行（动词）。

• fly 本词

  The common, everyday verb for moving through the air; used for birds, insects, aircraft, and even figurative speed; simple grammar, often followed directly by a direction.

  这是表示“在空中移动”最常见、最日常的动词，主语可以是鸟、昆虫、飞机等，也可用于比喻速度快；语法简单，常直接接方向状语。

  The geese fly south every autumn before the lake freezes.

  每年秋天，湖水结冰之前，大雁都会飞往南方。

• wing

  A literary or old-fashioned verb for flying, most often used in the fixed phrase 'wing one's way'; rare in everyday speech and mainly found in descriptive or poetic writing.

  这是一个较为文学化、老式的“飞行”说法，常出现在“wing one's way”这样的固定搭配里，日常口语中很少使用，多见于描写性或诗意的文字。

  The eagle winged its way across the valley toward the distant mountains.

  那只老鹰飞越山谷，飞向远方的群山。

Both words can mean to fly. Fly is the common, everyday verb, used for birds, insects, and aircraft. Wing as a verb is literary and old-fashioned, mostly in the phrase 'wing one's way', and rare in speech. Wing as a noun is not compared.

这两个词在该义项上都表示“在空中移动、飞行”，但fly是最常见、最日常的说法，wing作动词表示“飞行”则较为文学化、老式，日常口语中很少使用。这里不比较wing作名词“翅膀”或“擦伤翅膀、射伤”等其他意思。
