COMPARATIVE VIEW OF THE FOUR CONJUGATIONS.

243. The Four Conjugations, it will be seen from this table, differ from each other only in the formation of the Principal Parts and in the endings of the Present System.

244. But by a close analysis it will be found

1. That even these differences in a great measure disappear, and that the four conjugations become only varieties of one general system of conjugation.

2. That these varieties have been produced by the union of different final letters in the various stems with one general system of endings.

245. According to this analysis

1. The stems in the four conjugations end in the following letters:

2) For Other Parts:-the endings given above for the third conjugation, but in the Future, bo and bor are regular endings as well as am and ar, and in the Infinitive Passive, ĕri as well as i. 3. The manner in which these endings unite with the different stems may be seen in the following

COMPARATIVE VIEW OF CONJUGATIONS.

1 The Passive has the same changes as the Active: ama-or amor; ama-ĕris

=amāris; mone-ĕris = : monēris; audi-ĕris = audīris, etc.

2 A changed to e, so throughout; ama-as = ames, etc.

FORMATION OF PRINCIPAL PARTS.

246. The general rule for obtaining these forms has already been given (240), but as they are the basis of all verbal inflections, a fuller treatment of the subject is desirable. We notice

I. Regular Formations.

II. Irregular Formations.

I. REGULAR FORMATIONS.

247. The Principal Parts of verbs in the four conjugations are formed with the following endings:'
