What we are trying to express is the sentence-scope adverb "necessarily(S)" which means "in all possible states of affairs, S" or more longwindedly "there is no possible state of affairs such that it is not true that S". For example: (1) {lo remna ne'e mabru} =3D Humans are necessarily mammals. =3D In all possible states of affairs, humans are mammals. (2) {ro nanmu je se mensi ne'e bruna} =3D All men with sisters are necessarily brothers. =3D There is no possible state of affairs such that it is not true that all men with sisters are brothers. --=20 You received this message because you are subscribed to the Google Groups "= lojban" group.
