Adsint discipuli ante lectionem, ne quis vocabulum novum neglegat.

Adsint is the third-person plural present subjunctive of adsum, which means to be present or to be here.

The verb is built from ad + sum, so it is related to sum. Its present subjunctive forms are:

adsim, adsis, adsit, adsimus, adsitis, adsint

So adsint discipuli means something like let the students be present.

Because this is not a simple statement of fact such as the students are present. It is more like an instruction, encouragement, or command.

Latin often uses the present subjunctive for a jussive subjunctive, especially in the third person. English usually translates this with let:

• adsunt discipuli = the students are present
• adsint discipuli = let the students be present

So the sentence is giving a recommendation or command, not merely describing a situation.

Discipuli is nominative plural. It is the subject of adsint.

Its dictionary form is discipulus, meaning student or pupil. Since adsint is third-person plural, the subject also needs to be plural.

Because ante is a preposition that takes the accusative when it means before in time or place.

So:

• lectio = nominative
• lectionem = accusative

Therefore ante lectionem means before the lesson.

This is a very common pattern:

• ante pugnam = before the battle
• ante cenam = before dinner
• ante lucem = before dawn

In this context, lectio most naturally means lesson, class, or possibly reading period, depending on the textbook or setting.

A learner may first meet lectio with the basic idea of reading, since it comes from a verb meaning to gather, choose, read. But in classroom Latin it often has the practical meaning lesson.

So ante lectionem is best understood as before the lesson.

Because ne introduces a negative purpose clause here.

The idea is:

Let the students be present before the lesson, so that no one may neglect a new word.

In Latin, purpose clauses normally use:

• ut
  • subjunctive for positive purpose
• ne
  • subjunctive for negative purpose

So ne quis vocabulum novum neglegat means so that no one may neglect a new word or lest anyone neglect a new word.

Because it is inside a clause introduced by ne, expressing purpose or prevention.

Neglegat is the third-person singular present subjunctive of neglego, meaning to neglect, ignore, or pay too little attention to.

Since the clause is a negative purpose clause, the subjunctive is required:

• ne ... neglegat

So the subjunctive here does not mean uncertainty. It is simply the normal grammar of this kind of clause.

This is a very common Latin pattern. After words such as si, nisi, num, and ne, Latin often uses quis as an indefinite pronoun, meaning anyone or someone.

So here:

• quis does not mean who?
• it means anyone

Therefore ne quis means lest anyone or so that no one.

A native English speaker often expects something more explicit like anyone, but Latin regularly uses quis in this environment.

Vocabulum novum is accusative singular. It is the direct object of neglegat.

• vocabulum = noun, neuter singular
• novum = adjective, neuter singular accusative, agreeing with vocabulum

So novum matches vocabulum in gender, number, and case.

Together they mean a new word or new vocabulary item.

Not necessarily in a very narrow sense. The singular can refer to a new word as a typical example, rather than stressing a specific single word only.

English often works similarly:

• Do not ignore a new word
• Always write down an unfamiliar word

The focus is on the category or typical instance. Latin does this naturally with the singular.

The sentence has:

1. a main clause with a jussive subjunctive
   Adsint discipuli ante lectionem
2. a subordinate negative purpose clause
   ne quis vocabulum novum neglegat

So the logic is:

Let the students be present before the lesson, in order that no one may neglect a new word.

Or a bit more naturally:

Let the students be present before the lesson, so that no one misses a new word.

Yes, but in a normal Latin way. Latin word order is much more flexible than English word order.

This sentence begins with adsint, which gives a slight sense of urgency or emphasis to the command. Then comes the subject discipuli. The phrase ante lectionem is placed before the purpose clause to set the time clearly.

A different order, such as Discipuli ante lectionem adsint, would also be grammatical. The meaning would stay basically the same, but the emphasis would shift slightly.

So in Latin, word order often helps with focus and style, not just basic grammar.
