Summary

G. J. Adler A Practical Grammar of the Latin Language… (1858)

Iste has always reference to the person spoken to, and is hence called the pronoun of the second person; as iste liber, istud saccharum, that book, that sugar (of yours or mentioned by you) . It sometimes conveys the notion of disapprobation or contempt, as ille does that of honor; an iste homō, this fellow; ille Sōcratēs, the well-known (illustrious) Socrates. Is, when used as a demonstrative, points to a person or thing already mentioned, in the sense of the English "this man," "that thing" (of which I am speaking or have just spoken) , or of an emphatic "he, she, it"

C. The pronoun hic, in connection with ille and iste, gives rise to compounds istic (or isthic) , istaec, istoc or istuc, and illic, illaec, illoc or illuc, both of which are decline like hic, haec, hoc. B. Obs. The adversative conjunctions sed and vērum2 are nearly synonymous, and are always placed at the beginning of the clause introduced by them. Autem, like the English "however," generally stands after the first, second or third word. Examples:— Exercise 12. See the answers here.
