Cоmplementаry infinitives Infinitives in Lаtin serve severаl functiоns. In additiоn to helping us form the present stem of the verb, infinitives can also be used in sentences as "complements" of verbs like dēbeō, dēbēre. When used like this, we call this a complementary infinitive. When we see a complementary infinitive, we will have to think about how best to translate it with the verb it goes with. As have seen, dēbeō, dēbēre has several possible translations. Taken on its own, this verb usually means "to owe", as in "I owe a debt" ("debt" in English is derived from the fourth principal part, dēbitum!). But when it is complemented by an infinitive, one of the other translations -- "ought, must, should" -- is more suitable. The phrase dēbēs cōgitāre, for example, could be translated: "you ought to think" "you must think" See how some verbs in English retain the word "to" when using a complementary infinitive, but others don't. What this shows us is that when we read vocabulary lists, we should keep an eye out to see if there are distinctions in how the verb is translated. Meanings separated by commas are usually equivalent (or "synonyms"), but those separated by a semi-colon usually indicates a distinct usage that might be more applicable depending on how it fits in the rest of the sentence.

The Pаssive Vоice аnd Present Pаssive System: intrоductiоn In this module, we will begin to look at the passive voice in Latin. Up till now, when we have met a verb, it has been in the active voice: the subject of the verb is the same as the person or thing doing the action of the verb (I praise, they were warning, you will lead, she has heard). Now, in the passive voice, the subject is the target of the action (I was praised, they were being warned, you will be led, she has been heard). Let's get started with this video outlining some of the basics of the passive voice!
