I admit it has been many years since I studied a Latin verb for the first time. However, I recently had the opportunity to work on Greek verbs in the present tense with one of my friends. It reminded me of two things: first, Greek is so much easier to learn after knowing Latin and learning the Greek alphabet and second, one must have a plan in order to study successfully.
Here is how I go about teaching Latin verbs (and also a handout). First, I always start with the English because we always want to start with what they know. I review definitions such as transitive and intransitive, principal parts, tenses, and conjugations of English verbs (I love, you love, he/she/it loves, we love, you all love, they love). Verb persons are always a bit tricky to describe. Students, however, love to discuss point of view in novels and the fact that first person point of view has a narrator in on the action and third person point of view has a narrator who is apart from the action. Principal parts are like verb DNA and show us how we can form every form of the verb (over 300 forms). After I am certain students have a working definition of a verb in English, we move on to Latin.
