"His socks are black."
Translation:Liaj ŝtrumpetoj estas nigraj.
If it is possible to say "Glacio malvarmas," meaning that ice is cold - making an ajective (malvalrma) into a verb (malvarmi), is it then possible for something that is white (Gxi estas blanka) to also "be white" in the same way, in other words "gxi blankas"? Is it also, by the same token, possible that something is black, saying "gxi nigras"? Please advise.
