Words ending in ize, ise, and yse.
In English we have a few verbs ending in ise, though ize is the regular ending of most verbs of this class, at least according to the American usage. In England ise is often substituted for ize. The following words derived through the French must always be written with the termination ise:
advertise catechise compromise devise divertise exercise misprise supervise advise chastise criticise disfranchise emprise exorcise premise surmise affranchise circumcise demise disguise enfranchise franchise reprise surprise apprise comprise despise disenfranchise enterprise manumise
A few words end in yse (yze): analyse, paralyse. They are all words from the Greek.
Words ending in cious, sion, tion, etc.
The common termination is tious, but there are a few words ending in cious, among them the following:
avaricious pernicious tenacious capricious suspicious precocious judicious vicious sagacious malicious conscious
The endings tion and sion are both common; sion usually being the termination of words originally ending in d, de, ge, mit, rt, se, and so, as extend——extension.
Cion and cian are found only in a few words, such as suspicion, physician. Also, while tial is most common by far, we have cial, as in special, official, etc.
Special words with c sounded like s.
