Questions & Answers about La vorto estas bona por ni.
Why do we say "La vorto" instead of "La vorton"?
Because vorto serves as the subject and complements estas, so it stays in the nominative form without the accusative -n ending. In Esperanto, the accusative -(n) is generally used for direct objects or to indicate movement, but here we have a simple statement of being.
Why is "bona" in this sentence and not "bonan" or "bonaj"?
In Esperanto, adjectives agree in number and case with the nouns they describe. Since vorto is singular and nominative, the adjective bona must also be singular and nominative.
Why do we use "por ni" to express "for us"?
Por translates directly as "for." It signifies the concept of "in favor of" or "for the benefit of" someone or something. Hence, por ni means "for us," highlighting that the word is good in relation to us or beneficial to us.
Why do we say "estas" instead of another verb like "havas" or "faras"?
Estas is the Esperanto verb "to be," used for linking a subject with its description. Here, it connects La vorto (the subject) to its quality bona (the adjective). Verbs like havas (to have) or faras (to do/make) would change the meaning entirely.
