Last, but not least, every word parses itself by its distinctive ending.

(7) The stupendous flexibility of Esperanto will be still better understood if I state here that it possesses some 30 particles (prefixes and suffixes), each with a definite meaning and each available whenever you want to attach that particular meaning to any word.

We have already seen that the suffix “in” expresses the female sex whenever it may be desirable to give it expression.  So “id” denotes the offspring, “il” the tool or instrument, “isto” the profession, “ul” the person or individual, “ec” the quality (abstract), “ajx” the concrete thing, product, or result, “eg” means large, and “et” small, etc.  Now, let us see how this works out in practice.  Bovo is bull; bovino, cow; bovido, calf; bovajxo, beef; bovidino, female calf.  And you may say bovego, boveto, bovinego, bovineto, bovidego, bovideto, bovidinego, and bovidineto if you wish to add the idea of size or smallness to the original or to the derived word.

Again:  “Lern” is the root for learning.  We first get lerni, to learn; lerna, learned; lerne, learnedly; learno, learning.  Next, using a few of the particles we can make:  lernebla, capable of being learned; lernema, inclined to learn (studious); lerninda, worth learning; lernilo, a text book (a tool); lernisto (a professional learner), a student; lernulo, a learned person, a scholar; lerneco, learning in the abstract; lernajxo, the matter to be learned (concrete), etc.  And once more note that what you can do with one root you can do with every root in the vocabulary.  So that the originally available number of words is multiplied ten and hundred fold.  Which simply means a tremendous saving of labor in learning words and forms and yet secures a range of expression and a degree of precision undreamed of in any other language.

(8) On the possible rivals, past, present, or future, to Esperanto see closing remarks.

(9) To complete what I said on the verb during the hearing I give here the entire paradigm of the verb in Esperanto.

Paroli, to speak; parolanta, speaking; parolata, spoken.

Present, I speak, etc.:  Mi parolas, vi parolas, li parolas, sxi parolas, ni parolas, vi parolas, ili parolas, oni (one) parolas, gxi (it) parolas.

There a thus only one ending “as” for the present of every verb and the same for every person.

In the past the ending is “is”:  mi parolis, I spoke, etc.

In the future “os” mi parolos, I shall speak, etc.  In the conditional “us”:  mi parolus, I should speak, etc.  In the subjunctive “u”:  ke mi parolu, that I may or might speak, the tense being sufficiently indicated by the antecedent verb.

For the imperative we use the subjunctive without conjunction and generally without subject.

The participle has a most ingenious flexbility, it having three forms, anta, inta, onta for the active, and ata, ita, ota for the passive; parolanta, speaking now; parolinta, having spoken; parolonta, about to be speaking; parolata, being spoken now; parolita, spoken formerly; parolota, to be spoken later.
