259 (11). El = Out of.
El is the opposite of en = in, but only when movement in and out is implied.
Care must be taken not to confuse el with da or de, both of which also signify "of," that English preposition with so many meanings. El means essentially "out of," denoting that the noun specified is a portion of something, or is made of some particular material, or issues from something (see par. [259 (7)]).
