Post imbrem hortus placidior videtur, et ros in herba iterum lucet.

Because post is a preposition that takes the accusative when it means after. So:

• post imbrem = after the rain

The basic dictionary form is imber, imbris (rainstorm, rain), and imbrem is its accusative singular form.

Latin often expresses time relationships with a preposition + noun rather than an adverb. So instead of saying something like afterward, the garden seems calmer, it can say after the rain, the garden seems calmer.

This is a very normal Latin way to set the scene at the beginning of a sentence.

Hortus is the subject of videtur. The sentence is saying that the garden seems calmer, so the garden is the thing doing the seeming.

That is why hortus is in the nominative singular:

• hortus = the garden

Placidior is a comparative adjective. It means calmer, more शांत—in English, more calm or simply calmer.

It agrees with hortus:

• hortus = masculine singular nominative
• placidior = masculine/feminine singular nominative comparative

So hortus placidior means the garden, calmer or more naturally the garden seems calmer.

A comparative in Latin does not always need an explicitly stated second term. Placidior can simply mean:

• calmer
• rather calm
• calmer than before
• calmer than it was earlier

Here the comparison is understood from the context: after the rain, the garden seems calmer than before the rain. Latin often leaves that unstated when it is obvious.

Videtur is actually the passive form of videre (to see), but in Latin that passive form often means seems or appears.

Literally, it comes from the idea it is seen. From there, it develops the meaning:

• hortus placidior videtur = the garden seems calmer

This is a very common Latin usage.

Yes. Videtur is third person singular, and it matches the singular subject hortus.

• hortus ... videtur = the garden seems

If the subject were plural, you would expect a plural verb, for example videntur.

In the second half of the sentence, ros is the subject of lucet.

• ros = dew
• lucet = shines

So ros must be nominative singular. Its dictionary form is ros, roris.

In in herba, the noun herba is in the ablative singular because in with the ablative usually indicates location:

• in herba = in the grass

If in took the accusative, it would usually suggest motion into something. But here the dew is already there, so Latin uses the ablative.

Latin in with the ablative can cover meanings that English divides into in, on, and sometimes among, depending on context.

So in herba can naturally be translated as:

• in the grass
• on the grass
• among the grass

English chooses the wording that sounds most natural, but the Latin expression itself is perfectly normal.

Iterum means again. It tells you that the dew is shining once more, presumably after being obscured or less noticeable during the rain.

So:

• ros in herba iterum lucet = the dew in the grass shines again

It adds a sense of renewed brightness.

Latin word order is more flexible than English word order because case endings show the grammatical relationships.

This sentence is arranged in a natural Latin way:

• Post imbrem sets the time first: after the rain
• hortus placidior videtur presents the main observation
• et adds a second related image
• ros in herba iterum lucet finishes with the dew shining again

Latin often places important scene-setting phrases early and lets the verb come later. The order is not random; it helps the sentence flow and emphasizes the imagery.

Yes. Depending on context, placidior could be rendered as:

• calmer
• more peaceful
• more tranquil
• quieter

All are reasonable, because placidus suggests calmness and peaceful stillness. The best English choice depends on the tone of the translation.

Classical Latin has no definite or indefinite article. So nouns like hortus, imber, ros, and herba do not automatically include words like the or a.

The translator supplies them from context:

• hortus = the garden or a garden
• ros = the dew
• herba = the grass

In this sentence, English naturally uses the for all of them.

Here is a quick breakdown:

• Post — preposition, takes the accusative
• imbrem — accusative singular, object of post
• hortus — nominative singular, subject of videtur
• placidior — comparative adjective, describing hortus
• videtur — verb, seems / appears
• et — and
• ros — nominative singular, subject of lucet
• in — preposition
• herba — ablative singular after in, showing location
• iterum — adverb, again
• lucet — verb, shines
