Suspensura bipedalis est.

• suspensura is the subject. It is nominative singular feminine.
• bipedalis is a predicate adjective describing the subject. It is also nominative singular feminine.
• est is the verb is, from sum, esse.

So the sentence has a very common Latin pattern:

subject + predicate adjective + est

Because with the verb sum (to be), Latin normally puts both the subject and its complement in the nominative.

In English, we say:

The wall is high.

Here, wall is the subject, and high describes it. Latin does the same kind of thing:

• suspensura = the thing being talked about
• bipedalis = the description applied to it

So both stay in the nominative, because bipedalis is not an object; it is part of what the subject is.

Because bipedalis is a third-declension adjective.

Its dictionary form is typically given as:

bipedalis, bipedale

That means:

• bipedalis = masculine/feminine nominative singular
• bipedale = neuter nominative singular

Since suspensura is feminine singular, the matching form is bipedalis.

So the -is ending here is exactly what you expect for a masculine/feminine nominative singular third-declension adjective.

That is a very good question, because -is can indeed be a genitive singular ending in the third declension.

But here the syntax makes the meaning clear. After est, Latin expects a predicate noun or predicate adjective that matches the subject. Since suspensura is nominative singular feminine, bipedalis is understood as nominative singular feminine too.

If bipedalis were genitive here, you would normally expect a different structure, usually with another noun depending on it.

So although the form is potentially ambiguous by itself, the sentence pattern tells you how to read it.

Because Latin does not have articles like English a, an, or the.

So a Latin noun like suspensura can mean:

• a suspensura
• the suspensura
• sometimes just suspensura in a general sense

You decide from the context, not from a separate word.

This is something English speakers have to get used to: Latin often leaves things unstated that English requires.

In Latin, word order is much more flexible than in English.

So:

• Suspensura bipedalis est
• Bipedalis suspensura est
• Suspensura est bipedalis

can all be grammatical, though the emphasis may change slightly.

Putting bipedalis after suspensura is perfectly normal. Latin does not have a single fixed rule like English does for adjective placement.

Also, because bipedalis is a predicate adjective here, it is not simply sitting next to the noun as an ordinary attributive adjective. It is part of the statement made with est.

Est is the third-person singular present indicative of sum, meaning is.

Its job is to link the subject with a description. It does not show action in the usual sense; it works as a copula, a linking verb.

So in this sentence:

• suspensura = the subject
• bipedalis = the description
• est = the link between them

This is one of the most basic and important sentence types in Latin.

Sometimes, yes. Latin can omit forms of sum, especially in concise styles, poetry, inscriptions, or when the meaning is obvious.

So a shortened version like Suspensura bipedalis could occur in the right context.

However, with est included, the sentence is fully explicit and straightforward. For a learner, seeing est is helpful because it clearly marks the sentence as X is Y.

In a reconstructed Classical pronunciation, an approximate guide would be:

soos-pen-SOO-ra bi-pe-DAA-lis est

A few details:

• u sounds like oo
• e sounds like eh
• i sounds like ee
• the stress falls on -sū- in suspensūra
• the stress falls on -dā- in bipedālis

So the rhythm is:

sus-pen-SŪ-ra bi-pe-DĀ-lis est

They are related, but you should not automatically assume they mean exactly the same thing in every context.

English bipedal usually means having two feet or walking on two feet.

Latin bipedalis, however, often means measuring two feet in length, height, width, or some other dimension, especially in technical or architectural language.

So even though the words are related, the Latin word may be used in a more specific measurement sense than the modern English word suggests.
