Questions & Answers about Ĵaŭdo estos longa tago por ni, ĉar ni havos kunvenon je la oka.
Why is Ĵaŭdo capitalized? Are days of the week normally capitalized in Esperanto?
Not usually. In Esperanto, days of the week are normally written in lowercase, just like ordinary nouns: lundo, mardo, merkredo, ĵaŭdo, and so on.
Here it is capitalized simply because it is the first word of the sentence.
So:
- ĵaŭdo = Thursday
- Ĵaŭdo = Thursday at the beginning of a sentence
What does estos mean, and how is it formed?
Estos is the future tense of esti = to be.
Esperanto verb endings are very regular:
- estas = is / am / are
- estis = was / were
- estos = will be
- estus = would be
- esti = to be
So Ĵaŭdo estos longa tago means Thursday will be a long day.
Why is it longa tago and not longan tagon?
Because longa tago is the predicate after the verb esti.
After esti, Esperanto does not use the accusative -n for the complement. So:
- Tio estas bona ideo. = That is a good idea.
- La tago estos longa. = The day will be long.
In your sentence, longa tago describes what Thursday will be, so no -n is needed.
