The term 'comparison conjunction' refers to a type of conjunction used to compare two things. The most common example of this type of conjunction is the word 'than, ' which is used to compare two things in terms of size, quantity, or degree. For example, one might say 'I am taller than my brother, ' or 'I have more money than I did last year.' In this way, comparison conjunctions are an important part of the English language and are used to make comparisons between two things.
