Are they the king's "invisible" pants that only wise people can see? :)
The preposition ל- can be translated to either "for" or "to", depending on context.
The suggestions are out of context. A known Duo limitation.
Yes! And there is a word that can be translated to for and to in my native language, too. (The word is para, and the language is Portuguese)
Yes. In Portuguese there are two prepositions for "for" and "to", that are "para" and "a", but they haven't exact translations in English and in Hebrew (the same with french "pour" and "a") (sometimes they represent "for" and "to", but in practice it's pretty rare to occour)...
