Yes, there is a difference between the terms "mentally handicapped" and "mentally ed." However, it's important to note that the terminology surrounding intellectual disabilities has evolved over time, and there is ongoing discussion about the appropriate language to use. I will explain the historical context and provide some guidance on how to approach this topic respectfully.

In the past, the term "mentally ed" was commonly used to describe individuals with intellectual disabilities. However, this term has now fallen out of favor due to its negative connotations and potential to stigmatize individuals. Many advocacy groups and professionals now prefer the term "intellectual disability" or "developmental disability."

The term "mentally handicapped" is also considered outdated and not widely used today. However, it may have been used in the past as another way to describe individuals with intellectual disabilities.

It's essential to emphasize that language evolves, and what is considered appropriate can vary depending on cultural and societal norms. When discussing intellectual disabilities, it is best to use person-first language, which places the individual before their disability. For example, saying "a person with an intellectual disability" is generally preferred over labeling someone as "mentally ed" or "mentally handicapped."

It is always advisable to speak with sensitivity and respect when discussing such topics. If you are interacting with individuals or groups who have direct experience with intellectual disabilities, it's crucial to listen to their preferences and follow their lead in choosing the appropriate language.
