Testudo lente ambulat.

• testudo = the subject, tortoise
• lente = an adverb, slowly
• ambulat = the verb, walks / is walking

So the structure is:

subject + adverb + verb

Latin does not have articles like English the and a/an.

So testudo can mean:

• the tortoise
• a tortoise
• sometimes just tortoise, depending on context

English has to choose an article, but Latin usually leaves that to context.

Testudo is nominative singular, which is the form normally used for the subject of a sentence.

Here, testudo is the one doing the action, so nominative makes sense.

It is also a feminine noun in Latin.

Because lente is an adverb, not an adjective.

• An adjective describes a noun: slow tortoise
• An adverb describes a verb: walks slowly

In this sentence, the word is describing how the tortoise walks, so Latin uses the adverb lente.

If you said testudo lenta, that would mean a slow tortoise, not the tortoise walks slowly.

Ambulat is:

• present tense
• third person singular
• active
• indicative

It comes from ambulare, meaning to walk.

So ambulat means he/she/it walks or is walking.

Because testudo is singular, the verb is singular too.

The verb form ambulat only tells you third person singular: he, she, or it.

The noun testudo tells you what the subject is: a tortoise. In English, that is usually translated as it, though sometimes a translator may choose she for an animal.

So Latin grammar gives you third person singular, and the noun supplies the actual subject.

Yes. Latin word order is much more flexible than English word order.

You could also see:

• Lente testudo ambulat
• Ambulat testudo lente
• Testudo ambulat lente

All of these can still mean basically The tortoise walks slowly.

However, Testudo lente ambulat is a perfectly natural, straightforward order. Different orders can shift emphasis.

Yes. Latin often leaves out the subject when it is clear from context.

Because ambulat already means he/she/it walks, a Latin speaker could say:

Lente ambulat = He/She/It walks slowly

But if you want to state explicitly that it is the tortoise, you include testudo.

In restored Classical pronunciation, it is approximately:

tes-TOO-do LEN-teh AM-boo-lat

A few helpful points:

• u is pronounced like oo
• e is pronounced like eh
• t is always a clear t
• the stress usually falls on:
  • tes-TU-do
  • LEN-te
  • AM-bu-lat

Because lente is an adverb, and adverbs do not agree with nouns.

Agreement happens with adjectives, not adverbs.

For example:

• testudo lenta = the slow tortoise
  Here lenta is an adjective and agrees with testudo.
• testudo lente ambulat = the tortoise walks slowly
  Here lente is an adverb and modifies ambulat, not testudo.

Not always. Testudo literally means tortoise, but in Latin it can also be used in other senses, especially by extension of shape, such as:

• a tortoise-shell object
• a military testudo formation

But in this sentence, the ordinary animal meaning is the natural one.
