why the pronunciation for coronel?
 The Spanish understood the word ‘coronel’ as the officer of the ‘crown’ rather than that of the ‘column’. It is possible that both the French and the Spanish pronunciation affected the English one. The English had already begun to use the word ‘coronel’, which became bastardized by their accent to be pronounced as ‘kernel’, with an open ambiguous ‘r’ in the middle overshadowing the ‘o’.
