LESSON XXV.THE INTERROGATIVE ADJECTIVE.
112. The interrogative adjective related to the interrogative pronoun kiu, is kia, what kind of, what sort of:
Kiajn vestojn li portis? What sort of clothes did he wear?
Kian panon vi preferas? What kind of bread do you prefer?
Mi miras kia persono li estas, I wonder what sort of a person he is.

THE IMPERFECT TENSE.
113. The compound tense formed by using the present active participle with the past tense of esti represents an act or condition as in progress in past time, but not perfected, and is called the imperfect tense. The conjugation of vidi in this tense is as follows:
mi estis vidanta, I was seeing.
vi estis vidanta, you were seeing.
li (ŝi, ĝi) estis vidanta, he (she, it) was seeing.
ni estis vidantaj, we were seeing.
vi estis vidantaj, you were seeing.
ili estis vidantaj, they were seeing.
THE PROGRESSIVE FUTURE TENSE.
114. The compound tense formed by using the present active participle with the future tense of esti represents an act or condition as in progress—or a condition as existing continuously—at a future time, and is called the progressive future tense. The conjugation of vidi in this tense is as follows:
mi estos vidanta, I shall be seeing.
vi estos vidanta, you will be seeing.
li (ŝi, ĝi) estos vidanta, he (she, it) will be seeing.
ni estos vidantaj, we shall be seeing.
vi estos vidantaj, you will be seeing.
ili estos vidantaj, they will be seeing.
SALUTATIONS AND EXCLAMATIONS.
115. When the word or words expressing a salutation or exclamation may be regarded as the direct object of a verb which is not expressed; these words are put in the accusative case:
Bonan matenon! Good morning! (I wish you "good morning.")
Bonan nokton! Good night! (I wish you a "good night.")
Multajn salutojn al via patro! (I send) many greetings to your father!
Dankon! Thanks! (I give to you "thanks.")
Ĉielon! Heavens! (I invoke the "heavens.")
WORD FORMATION.
116. The majority of roots have such a meaning that at least two kinds of words, and often three or four, may be formed from them by use of the general endings for verbs, nouns, adjectives and adverbs. (Each root will hereafter be quoted but once in the vocabularies, with a hyphen separating it from the ending with which it appears first in the reading lesson, or with which it is most frequently used.) Following are examples of word formation from roots already familiar:
