Prepositions
Spanish has a relatively large number of prepositions, and does not use postpositions. The following list is traditionally recited:
A, ante, bajo, cabe, con, contra, de, desde, en, entre, hacia, hasta, para, por, según, sin, so, sobre, tras.
Lately, two new prepositions have been added: "durante" and "mediante", usually placed at the end to preserve the list (which is usually learnt by heart by Spanish students).
This list includes two archaic prepositions (so and cabe), but leaves out two new Latinisms (vía and pro) as well as a large number of very important compound prepositions.
Prepositions in Spanish do not change a verb's meaning as they do in English. For example, to translate "run out of water" "run up a bill" "run down a pedestrian" "run in a thief" into Spanish requires completely different verbs, and not simply the use of "correr" ("run") plus the corresponding Spanish prepositions. This is more due to the nature of English phrasal verbs rather than an inherent function of Spanish verbs or prepositions.
