What is the subject of this sentence supposed to be? The translation that was marked right for me is "After the first hour is early" which is rather confusing in English. Is there a missing "it"? So it could read "After the first hour it is early" with an implied still before early?
This sentence seems to need "still" added to it as in "... it is still early", only we haven't been taught how to say that yet in Latin. Surely Latin has a way of conveying that sense.
Also, more importantly, can't "mane" be translated by "in the morning"? Going by this sentence, "mane " seems to mean "early in the day" and, previous to this, Duo gave us a picture of a sunrise and the caption "morning" and we were expected to twin it with the Latin "mane".
In translating previous examples I've taken "mane" to have the sense of "before schedule" rather than "early in the day". I presume it can be used in both senses.
Okay, this translation is borderline incomprehensible to me. At first I thought it was supposed to mean "it's past one o'clock in the morning" or "It's after 1 AM", with an implied "it" as the subject and everything else but the verb as the object, thus taking the accusative case (primam horam). But the translation implies that "after the first hour" is the subject of the sentence and "early" is akin to a predicative (as in the object of a linking verb), so how come it doesn't take the nominative case ("post prima hora manis est")?
Thanks for the in-depth explanation, it was very thoroughly and I highly appreciate it. As a native speaker of a Romance language, and having learned a couple of other Romance languages throughout my life, all the examples you listed make sense to me. The infinitive is our go-to verb form whenever a verb functions as a noun (as opposed to English, in which the gerund is the preferred form) and the double-accusative also makes perfect sense if there are two verbs (amo and video) that take a direct object, joined by reported speech. Come to think about it my issue with this "post primam horam mane est" is not so much with the Latin itself (since I am no expert in Latin), as it is with the English translation. "After the first hour is early" sounds rather clunky as a standalone sentence, and I literally see no reason as to why the tranlation doesn't show up as "it's early after one o'clock".
I think some grammarians may consider post primam horam as the subject but that's not overly important.
I think the course as is doesn't fully explore how forms of esse (here est) can link words together, since sometimes they won't be a standard noun in the nominative.
Sometimes you will see an infinitive used as the subject, such as the saying: Errare humanum est ('To err is human').
Sometimes you will see esse linking two accusatives together. Like in this example sentence (hope I don't make any mistakes): Marcus Liviam quam amicam suam est videt ('Marcus sees Livia who is his friend').
I hope this gets explained better at some point since that may help (I am sure my explanation will not be sufficient).
