Esperanto grammar

Esperanto is the near widely used constructed language spoke for international communication; it was intentional with highlygrammatical rules, & as such(a) is considered an easy Linguistic communication to learn.

Each part of speech has the characteristic ending: nouns end with ‑o; adjectives with ‑a; present‑tense indicative verbs with ‑as, & so on. An extensive system of prefixes and suffixes may be freely combined with roots to generate vocabulary, so that it is possible toeffectively with a vocabulary of 400 to 500 root words. The original vocabulary of Esperanto had around 900 root words, but was quickly expanded.

The article

Esperanto has a single definite article, la, which is invariable. it is similar to English "the".

La is used:

The article may also be used for inalienable possession of body parts and kin terms, where English would ownership a possessive adjective:

The article la, like the demonstrative adjective tiu this, that, occurs at the beginning of the noun phrase.

There is no grammatically so-called indefinite article: homo means either "human being" or "a human being", depending on the context, and similarly the plural homoj means "human beings" or "some human beings". The words iu and unu or their plurals iuj and unuj may be used somewhat like indefinite articles, but they're closer in meaning to "some" and "a certain" than to English "a". This usage of unu corresponds to English "a" when the "a" indicates a specific individual. For example, it is used to introduce new participants Unu viro ekvenis al mi kaj diris ... 'A man came up to me and said ...'.
