Question

Meaning in one word = evening full of the linnets wing ​

Answer 1

A linnet is a kind of bird that's like a finch. In other words, it's pretty small. Saying that the evening is full of linnet's wings makes us think not only of one bird, but also of all of them in flight. Now that's an image. The imagery is getting almost dreamlike—purple, hazy, full of birds in flight.
