Simon's form is interesting because it has been given the prosthetic vowel /e/ typical of Vulgar Latin and the Romance languages, cf.  Latin ''sc''(''h'')''ola'' > Old French ''escole'', Catalan/Galego/Portuguese: ''escola'', Spanish: ''escuela''. This sound change affected word-initial /sp-/, /st-/ and /sk-/.
