A Spanish word may be made up of one or two parts — a lexeme (lexema) and/or a morpheme (morfema). The lexeme is the word's basic meaning, so it is generally the word's root. For example, take the following words:

These five words share the root -cocin-, a lexeme that conveys the meaning of “cooking.” The particles -a, -ar, -ero, -eta, pre-, and -ado (a prefix and five suffixes) may be called morphemes — they don't have a meaning on their own but do add meaning when presented together with the root.
