"Children like puppies and kittens."
Translation:Infanoj ŝatas hundidojn kaj katidojn.
"little humans"... 's got a certain alienesque feel to it. I LIKE IT.
ALL CHILDREN ARE NOW LITTLE HUMANS.
EDIT: lel I just realized "homido" is "human offspring", not "hometo" like I originally saw...
MI ŜATAS AMBAŬ, KAJ MI UZOS AMBAŬ. HOMETOJ ESTAS LA IDOJ DE HOMOJ- ILI ESTAS HOMIDOJ.
None. "esti" is the only active verb that does not require a direct object ending (passive verbs cannot describe an action that is made on someone). All other verbs require this ending, unless there is a preposition between the verb and the object (which makes it an indirect object) for example: "Mi vidas la domoN" "Mi eliras EL la domo" Although, in some cases there is a preposition but it is still a direct object, for example: "Mi eniras EN la domoN" (I walk INTO the house) But it does not necessarily depend on the preposition itself, it is more dependent of the use of it, for example: "Mi iras EN la parko" (I walk IN the park) Here 'en' is used as 'in' and in the previous example it was used as 'into'.
You can read more about the '-n' suffix and do some exercises about it here: http://eo.lernu.net/lernado/gramatiko/konciza/objekto.php This is a great site, and I think that it is much better for beginning learning Esperanto, it explains the basics much better and it has a forum and public chat room and private helpers.
Hope that helped!
Here you can find more explanations about it and also some exercises about prepositions and in which of them you use the '-n' suffix: http://eo.lernu.net/lernado/gramatiko/konciza/prepozicioj.php
If it's a transitive verb, it takes a direct object. Not all active verbs are transitive. Also, "active" is a grammatical category and shouldn't be confused with actual activity. (Just like how linguists say "noun class" instead of "grammatical gender" because grammatical gender has nothing to do with biological sex. It's from "genera", meaning type/kind/category.)
"Children like." Okay, what do they like? "Like" in this sense is a transitive verb and needs a direct object. "Children like baby animals."
"To be" is not an active verb at all, but a stative verb (also called a linking verb or a copula). It describes the state of something. It's like a great big equals sign. It does not take a direct object but rather a subject complement.
Some English verbs can be active or stative depending on how they're used.
Tom looks out the window. (active)
Tom looks tired. (stative)
In short, if the predicate reflects upon the subject, then you're probably dealing with a stative verb.
Additionally, Esperanto does not use the accusative (direct object) if a noun phrase is the object of a preposition (because that makes it an indirect object).
