The suffix in the word “logical” is “-ical.” This suffix is commonly used in English to form adjectives and indicates a relationship or pertaining to something.
In the case of “logical,” the root word is “logic,” which refers to reasoning conducted or assessed according to strict principles of validity. When we add the suffix “-ical,” it transforms the noun “logic” into an adjective, describing something that is related to or characteristic of logical reasoning.
So, to break it down: “logic” + “-ical” = “logical,” meaning relating to or based on logic. This helps us describe arguments, thoughts, or processes that are coherent and reasonable, enhancing our understanding of the principles of reasoning.
