Three major notes.
Starting at the smallest, please make a note regarding "est." We will be talkingmore about this verb very soon, but for now assume that the things on BOTH sides of the verb are the same case. it functions much like an equal sign. So the nominative nouns make anything ont he other side of the verb ALSO nominative. I believe the sentence I gave you was The ancient gate is large. Here both "ancient gate" and "large" are both nominative. Just strike the sentence from the list, actually, and we'll talk more about "est" later.
Secondly, and perhaps most importantly...
I've been following the general pattern of Wheelock's Latin, and I forgot, when I wrote out the first conjugation, that it also does the SECOND conjugation in the same chapter. It wouldn't matter except for the exercises and vocabulary assume that you know this. So here's the second declension.
Second Conjugation verbs ALL end in "ere" in the infinitive. Always. That is how you know. It's very important to memorize all the parts of a verb so that when you see it in another form you can remember what it looks like in the infinitive. The endings are the same, except for the characteristic "e".
first person singular (I) - O
second person singular (you) - S
third person singular (he, she, or it) - T
first person plural (we) - MUS
second person plural (you) - TIS
third person plural (they) - NT
Thus for the verb video the paradigm would look like this:
video "I see"
vides "You see"
videt "he/she/it sees"
videmus "we see"
videtis "you see"
vident "they see"
Note in the first person singluar, the "e" is still present. That is the other distinguishing characteristic of Second Conjugation verbs. When you see "eo" in the first person singular, it's Second Conjugation. And you need to remember which are which by memorizing all the principle parts.
The third thing which I forgot to tell you was how to form the imperative. The imperative is the tone of command. If I said "Give me your answers," "give" is an imperative verb.
Latin has both a singular and a plural form of the imperative. And after all the above, it's quite easy. All you do for the singular is drop the "re".
Thus, the singular imperative for our two verbs would be:
lauda or vide (Praise! OR See!)
The plural is formed by adding "te" to the stem. Thus:
laudate or videte (Praise! or See! addressing multiple people)
laudate me would be "Praise me!"
vide would be "See me!"
(And I put the !! in for emphasis. They're not always necessary.)
I'm sorry for the jumbled way of this. Please bear with me as I muddle through this too.
