The etymology of the phrase "latches on" can be understood by breaking it down into its individual components:
1. "Latch": The word "latch" originates from Middle English "lache" or "lacche", which come from Old English "læccan" meaning "to catch, seize, or grasp". It is related to the Old Norse "leka" and the Old High German "lacchen", both of which mean "to catch".
2. The preposition "on" indicates a connection or attachment to something.
When "latch" and "on" are combined, the phrase "latches on" is formed, which means to catch or seize onto something, typically figuratively rather than literally. It is commonly used to describe someone or something becoming deeply engaged or involved with a particular idea, concept, or person.
