Far from any questioning, spelling is characterized as one of the obstacles regarding the issuer's posture through the written modality of language. Countless words, because they are similar in terms of sound, put them in check, as is the case with the races “x/ch”, “l/u”, s/z.
Thus, given the grammatical particularities, more precisely with regard to the rules and their possible exceptions, it is necessary that we are attentive to them, with a view to overcoming such obstacles. Therefore, the article under discussion aims to emphasize the words that constitute the suffixes "-izar" and "-isar", which commonly become the target of these fearful questions. So let's see:
Subsidizing us in the word "exorcise", we have that this one comes from the Latin exorcise, whose meaning is tied to the sense of expelling demons through prayers: exorcising a possessed person. We found, therefore, that the traits related to the origin of a given word influence its spelling too much, given that "exorcise" is composed of the letter “z”, therefore, “exorcise” follows the same pattern.
This feature has a relevant impact so that we can understand how the occurrence related to the terminology in question actually materializes. The fact is that there is no suffix represented by “-isar”, what actually occurs is just the addition of the ending “ar”, since it integrates the set of words already spelled with the letter “s”. Let's look at some representative cases:
In the case of the suffix "-izar", it is derived from the Greek ending -izein, which was incorporated into the mother tongue through Latin -izare, whose materialization takes place in cases linked to nouns and adjectives, once ending in -ico, -ism and -ista. Thus represented:
Important note:
Still referring to the terminology represented by "-izar", there is a preponderant factor that prevails in this occurrence - the fact that it is related to words whose formation is neither restricted to the use of the "s" nor the "z", such as:
