Pagkakaiba sa mga pagbabagong ng "Silogismong pangkategorya"

walang buod ng pagbabago
 
Ang anyo nito ay AAA, dahil ang lahat ng pangungusap ay pangkalahatang pagpapatibay (universal affirmative). Kasunod namang tatalakayin ang anyo ng silogismong pangkategorya. Ngunit upang maunawaan ang larawan, kailangan munang ipaliwanag ang tatlong uri ng paksa (terms):
[[pangunahing paksa]] (major term), [[nakapailalim na paksa]] (minor term) at [[panggitnang paksa]] (middle term).
 
[[major term]], [[minor term]], and the [[middle term]]. The term occurring as the predicate of the conclusion is the major term. In the aforementioned syllogism B is the major term. The minor term is the term that occurs as the subject of the conclusion; C is the minor term. Finally, by process of elimination, it can be deduced that the middle term is the term which does not occur in the conclusion, but instead once in each premise. Accordingly, A is the middle term. The figure of a categorical syllogism can be known by identifying the four possible arrangements of the middle term. The figures are represented numerically 1-4
 
* 1 the middle term occupies the subject of the first premise and the predicate of the second premise
