sentences:  The single letter "x" is generally pronounced as in word-initial position and as otherwise.There are exceptions to these generalisations, often the result of loanwords being spelled according to the spelling patterns of their languages of origin or residues of proposals by scholars in the early period of Modern English to follow the spelling patterns of Latin for English words of Germanic origin.For the vowel sounds of the English language, however, correspondences between spelling and pronunciation are more irregular.
