Questions & Answers about La eklipso kaj la ekvinokso ne okazas hodiaŭ.
Because -o is the normal noun ending in Esperanto.
So:
- eklipso = a noun
- ekvinokso = a noun
This is one of the most important patterns in the language:
-o for nouns, -a for adjectives, -e for adverbs, and infinitive verbs usually end in -i.
la is the definite article, like English the.
So:
- la eklipso = the eclipse
- la ekvinokso = the equinox
It is repeated because both nouns are definite.
La eklipso kaj la ekvinokso is the clearest, most neutral way to say the eclipse and the equinox.
Also, la never changes form. It stays la whether the noun is singular, plural, subject, or object.
Because each noun is individually singular:
- one eclipse
- one equinox
The whole subject is plural in meaning because the two singular nouns are joined by kaj (and), but that does not force each noun itself to take -j.
So eklipso and ekvinokso stay singular, even though together they form a compound subject.
