usually connected with a certain definite modification of the original radical sense.

a. We have seen, indeed, that the tense-systems are also for the most part made from derivative-stems; and even that, in some cases, such stems assume the appearance and value of roots, and are made the basis of a complete conjugational system. Nor is there any distinct division-line to be drawn between tense-systems and derivative conjugations; the latter are present-systems which have been expanded into conjugations by the addition of other tenses, and of participles, infinitives, and so on. In the earliest language, their forms outside of the present-system are still quite rare, hardly more than sporadic; and even later they are — with the exception of one or two formations which attain a comparative frequency — much less common than the corresponding forms of primary conjugation.

997. The secondary conjugations are: I. Passive; II. Intensive; III. Desiderative; IV. Causative; V. Denominative.

a. The passive is classed here as a secondary conjugation because of its analogy with the others in respect to specific value, and freedom of formation, although it does not, like them, make its forms outside the present system from its present-stem.

I. Passive.

998. The passive conjugation has been already in the main described. Thus, we have seen that —

a. It has a special present-system, the stem of which is present only, and not made the basis of any of the remaining forms: this stem is formed with the accented class-sign य , and it takes (with exceptions: 774) the middle endings. This present-system is treated with the others, above, 768 ff.

b. There is a special passive 3d sing. of the aorist, ending in इ i: it is treated above, 842 ff.

c. In the remaining tenses, the middle forms are used also in a passive sense.

d. But the passive use of middle forms is not common; it is oftenest met with in the perfect. The participle to a great extent takes the place of a past passive tense, and the gerundive that of a future. On the other
