esteriormente
Esteriormente is a rarely used adverb in Spanish that is intended to mean later or afterward. In contemporary standard Spanish, however, it is not considered a common or accepted form, and the norm is to use posteriormente to express sequence in time. When encountered, esteriormente is usually treated as nonstandard, archaic, or a result of orthographic or typographical error.
