Sometimes the verb is the only word in the sentence. It can also tell you the time frame, interval, or "tense". When you parse a Latin verb, you deconstruct these and other facets of the Latin. Tense, as mentioned, refers to time. In Latin, there are 3 simple and 3 perfect tenses, a total of 6, and they come in both active and passive forms. The Indicative Mood is the most common and that's what this page is about. You need to make note of the mood when parsing a verb.
Latin/Lesson 5-Perfect Indicative
Latin tenses - Wikipedia
All verbs in English and Latin have "tense"; that is, they place their statement about action or being in time. We usually think of tense in terms of the speakers time: "I am flying" is called a present tense because my flying is presented as occuring at the very same time as my speaking about it. Compare "You were flying": in this sentence your flying is presented as being in the past with regard to my speaking. Similarly "They will fly" presents the action of their flying in the future.
How to Form Latin Perfect Tense Verbs
The perfect denotes an action either as now completed Perfect Definite , or as having taken place at some undefined point of past time Historical or Aoristic Perfect. The Perfect Definite corresponds in general to the English perfect with have; the Historical Perfect to the English preterite or past. Note— The distinction between these two uses is represented by two forms in most other Indo-European languages, but was almost if not wholly lost to the minds of the Romans. It must be noticed, however, on account of the marked distinction in English and also because of certain differences in the sequence of tenses.
The tense of a verb indicates when the action took place. Each of the six Latin and English tenses has its own use in a sentence. Luckily, each English tense can be paired up with each Latin tense because the pair share similarities in how they function. The perfect tense in both Latin and English function identically, reprieving the student from having to make translation adjustments. The perfect tense is formed with the third principal part of a Latin verb.
