Prepositions of place: в, на, у, к, из, с, от

Russian prepositions of place come in matching sets for где? (where), куда? (where to) and откуда? (where from):

• в (in, into) and из (out of): в школе, в школу, из школы
• на (on, at, onto) and с (off, from): на работе, на работу, с работы
• у (at someone's), к (to someone) and от (from someone): у врача, к врачу, от врача

Some places take на instead of в: работа, почта, вокзал, урок, концерт, улица, стадион, завод, экскурсия. A place used with в says 'from' with из; a place used with на says it with с. People always take у, к and от. Из, с, от, у are followed by the genitive, к by the dative. Before some consonant clusters the preposition adds an -о: во Франции, ко мне, со стола.
