It implies a fleeting or superficial reference to a subject without delving into significant detail or exploration. When someone "touches on" a subject, they provide a cursory acknowledgment or reference to it without engaging in a comprehensive analysis or extensive explanation.
This phrase is often used to describe situations where a speaker or writer mentions an idea or theme tangentially, without devoting substantial time or attention to it.

The term "touches on" indicates a brief or passing allusion to a concept, idea, or issue, rather than an exhaustive examination or detailed exploration. It conveys the idea that the subject is not the primary focus of attention but is nonetheless included within the broader discussion.
The word "touches on" is a phrase composed of two parts: "touches" and "on".
The verb "touch" comes from the Old French word "touchier", which means "to touch". This word was derived from the Vulgar Latin word "toccare", meaning "to touch" or "strike". The original meaning was physical contact with something or someone.
The preposition "on" has its roots in Old English and Germanic languages. It is often used to indicate a location or position of something.
In the phrase "touches on", the verb "touches" refers to making brief or incidental contact with something, while the preposition "on" indicates the subject or topic that is being briefly mentioned or discussed. Hence, "touches on" implies briefly mentioning, discussing, or considering a certain subject or point.
