Putting too much money or resources into a specific area or project, often leading to negative consequences.

Overinvestment → It is formed from "over-" (meaning excessively) and "investment" (from Latin "investire", meaning to clothe or put on). The word refers to the act of excessively putting resources into something, often beyond what is necessary or prudent.
Think of putting resources 'excessively' ('over-') into something you are 'clothing' or 'putting on' ('investing'). This helps you remember that overinvestment means putting too much into an investment.
