-que "and", -ve "or" and the question marker -ne are attached to the end of a word.
-que joins its word, or the clause it begins, to what goes before; translate "and" in front of the word it is on: bonorum malorumque "of good and of evil", qualisque "and what kind". -que … -que or et … -que can mean "both … and".
-ve means "or": eumve odisse "or to hate him", loquiturve "or speaks".
-ne on the first word of a sentence makes a yes/no question: videsne? "do you see?"; in an indirect question it means "whether". Do not confuse it with -nam on question words, which adds emphasis: cujusnam "of what … ever", quinam "who exactly".
Some common words end in -que but are single words, not "and": quisque "each", quoque "also", atque "and", itaque "therefore", neque "and not", utique "certainly", denique "finally", undique "from all sides", quandoque "sometimes".
