or when the c sounds as sh as in ‘glacier’,

or when the vowel sounds like ee as in ‘seize’,

or i as in ‘height’,

or when it shows up in compound words such as ‘albeit’,

or when it shows up in –ing inflections of verbs that end in e, like queueing,

or occasionally in technical words that have a strong etymological link to their parent languages such as ‘cuneiform’ and ‘caffeine’,

and in numerous other random exceptions such as ‘science’, ‘forfeit’, and ‘weird.’
