春暖花开、万物复苏，如约而至的不只是春天，还有爱、美好和希望。如何用英语描述春光的美好，一起来学习几个与春有关的词语吧。
1. Vernalagnia
Derived from lagneia, a Greek word meaning “lust,” vernalagnia is a more formal name for what’s otherwise known as “spring fever”—a brighter and often more romantic mood brought on by the return of fine weather in the spring. Vernalagnia来自希腊语单词lagneia（情欲），与spring fever（春心荡漾）意思相同，即因明媚的春光而变得更加愉悦而浪漫的情绪。Vernalagnia是一种比较正式的说法。
2.Reverdie
Borrowed into English in the late 1800s, the word reverdie has a long history in its native French dating back as far as the 14th century at least: Derived from a verb, reverdir, meaning “to become green again,” a reverdie is a song, poem or dance performed in celebration of the return of the spring.Reverdie（春日颂）来自法语，在19世纪末被借用到英语中，其历史悠久，至少可以追溯到14世纪，由动词reverdir（返青）派生而来。Reverdie指歌颂春回大地的歌曲、诗词或舞蹈表演。
3. Valentining
Since the 19th century, the chirruping of birds during the spring mating season is known as valentining.自19世纪以来，人们就用valentining来形容鸟儿在繁殖季节发出的唧唧喳喳声。
4. Chelidonize
If you want to be even more specific, though the verb chelidonize is a proper word for the chirping of swallows as they fly overhead. It derives from the Greek word for swallow, chelidon—which is also the origin of the 17th century adjective Chelidonian.如果你想把鸟叫声分得更详细，那么用chelidonize来形容燕子从空中掠过时啾啾吱吱的叫声更恰当。Chelidonize来自希腊语单词chelidon（燕子）。Chelidon也是17世纪出现的形容词Chelidonian的词源。
5. Chelidonian
As well as being used to describe anything the deep red color of a swallow’s throat, Chelidonian winds are warm spring winds, so called because they tended to start blowing around the same time that swallows and martins began to return in the spring.Chelidonian除了可以指代像燕子喉咙部位的深红色一样的颜色之外，Chelidonian winds还有和煦春风的意思，这样表述是因为春风轻拂大地之时正是燕子归巢的时候。
6. Erumpent [ɪ’rəmpənt], breard
A word for the re-emerging of plants above the ground in spring, the 17th century adjective erumpent describes anything that bursts forth. The very first appearance of a plant above the ground, incidentally, is called the breard.Erumpent是17世纪出现的形容词，有“冒出，开放”的意思，用来形容春天埋在地下的植物破土而出。顺便提一下，植物刚刚萌芽可以用breard表示。
7. Frondescentia, frondescent, frondescence [frɔn’desəns], and frondesces
According to an 18th century dictionary of botanical terms, Frondescentia is “leafing season,” or “the time of the year when plants first unfold their leaves.” Likewise, a plant that is frondescent is just beginning to bud or produce leaves; frondescence is the process of budding or producing leaves; and when a plant frondesces, then it grows or puts forth leaves or buds. All four of these come from the Latin word for “leaf,” frons.根据18世纪的植物学术语词典，frondescentia指发叶期，或一年间植物初次长叶的时期。可以用frondescent形容刚发芽或长叶的植物；frondescence指的是植物发芽或长叶的过程；当表示植物在长叶或发芽时，可以用frondesces。这4个单词都来自拉丁语单词frons（叶子）。
8. Floriage, floriation, and efflorescence /ɛflə’rɛs(ə)ns/
Coined in the 18th century, floriage is blossom, or the collective flowers of a plant or tree. Likewise, a floriation is a decoration made of flowers, while efflorescence is the development or production of blossoming flowers.Floriage出现在18世纪，意为花朵，或植物、树木开出的花簇。Floriation是由花朵制成的装饰品，而efflorescence则指开花的过程。
