Prosthesis in Spanish and Portuguese

Spanish and Portuguese insert a word-initial e to the front of words with an s and consonant. This is a form of epenthesis called prosthesis. It changes the beginning of the word from CC to VCC.
Here are examples of Spanish and Portuguese words with prosthesis.

escuela escola (school)
esfera esfera (sphere)
espagueti espaguete (spaghetti)
especial especial (special)
esponja esponja (sponge)
estación estação (station)
estadio estádio (stadium)
estado estado (state)
estilo estilo (style)
estructura estrutura (structure)

Spanish and Portuguese do not allow the sequence sC word-initially. The rule may be represented as follows: sC --> esC/ #_. The rule affects the distribution of word-initial segments and is governed by phonotactics.
