Bis aleam iacis.

Bis means twice.

It is an adverb, not an adjective or a noun. That means it modifies the verb iacis and tells you how many times the action happens.

So in Bis aleam iacis, bis answers the question How often do you throw the die? → twice.

Because aleam is in the accusative singular.

In this sentence, aleam is the direct object of iacis. It is the thing being thrown. Latin often marks the direct object with the accusative case.

• nominative: alea = a die
• accusative: aleam = a die, as the object of the verb

So:

• alea iacit = the die throws would be grammatically strange, because alea is the subject form
• aleam iacis = you throw a die, where aleam is the object

Grammatically, aleam is singular, so it means a die.

A native English speaker may hesitate here because English often uses dice very freely, but Latin is being more specific in form:

• alea = one die
• aleam = one die, as object
• aleae / aleas = dice, depending on case

Also, Latin words for gaming pieces can vary by context, so in some situations Romans might use other words too. But in this sentence, aleam is clearly one die.

Iacis is the 2nd person singular present active indicative of iacere / iacio, meaning to throw.

So iacis means:

• you throw
• or sometimes you are throwing, depending on context

The ending -is tells you the subject is you singular.

A quick breakdown:

• iacio = I throw
• iacis = you throw
• iacit = he/she/it throws

Because Latin usually does not need a separate subject pronoun.

The verb ending already tells you who the subject is:

• iacis already means you throw

So adding tu is usually unnecessary unless you want emphasis or contrast.

For example:

• Bis aleam iacis. = You throw the die twice.
• Tu bis aleam iacis. = You throw the die twice.
  This sounds more emphatic, like contrasting you with someone else.

Yes, it could be different. Latin word order is much more flexible than English word order because the endings show the grammatical roles.

This sentence puts bis first, which gives a little prominence to twice.

Other possible orders could include:

• Aleam bis iacis
• Iacis bis aleam
• Aleam iacis bis

These all keep basically the same core meaning, though the emphasis can shift slightly.

A very common tendency in Latin is to place the verb near the end, which is what happens here with iacis.

Because bis is an adverb, and adverbs normally modify verbs, adjectives, or other adverbs—not nouns directly in this way.

Here, bis tells you how many times the action of throwing happens:

• you throw → twice

It does not describe the noun aleam. If Latin wanted to describe two dice, it would use a different construction, not bis aleam.

So the structure is:

• bis = twice
• aleam = a die
• iacis = you throw

Together: you throw a die twice

Excellent question. There are two different Latin verbs that look similar in dictionaries:

• iacio, iacere, ieci, iactum = to throw
• iaceo, iacere, iacui = to lie, lie down, be situated

They are different verbs.

In Bis aleam iacis, the form iacis comes from iacio = to throw, not from iaceo = to lie.

A learner can mix them up because the dictionary forms look similar, but the meanings and principal parts are different.

In reconstructed Classical Latin, iacis is pronounced roughly ya-kis.

A few helpful points:

• i at the beginning before a vowel often sounds like English y
• so ia- sounds like ya-
• c is always hard in Classical Latin, like k
• so iacis ≈ ya-kis

And aleam is roughly a-le-am, with the vowels pronounced clearly.

Yes. The exact English translation can vary depending on context.

The Latin verb iacio basically means throw or cast, so both are possible in English:

• You throw the die twice
• You cast the die twice

If the context is gaming, cast can sound especially natural in English.

Because bis tells you the action happens twice, not that there are two objects.

So the sentence means something like:

• You throw a die two times

It does not necessarily mean there are two dice. The same die could be thrown twice.

This is a common point for English speakers: number of actions and number of objects are separate ideas in Latin, just as they are in English.
