What term is used for a comparison of two objects or subjects?

The term that is commonly used for a comparison of two objects or subjects is "than." This word functions as a conjunction used in comparative statements to show the relationship between two items. For instance, when you say "A is larger than B," "than" establishes the comparison between A and B. This term helps to differentiate between them based on a particular characteristic or quality, such as size, quantity, or degree.

The other terms mentioned here do not serve the purpose of making comparisons. "Then" typically refers to a time-related sequence or consequence. "Both" indicates two things considered together but does not inherently establish a comparative relationship. "Either" suggests a choice between two options, which again does not directly relate to the act of comparison. Thus, "than" is the precise term needed to articulate a comparison.
