Words matter.

My view is, he term "giver" denotes a "taker" as well. The term "partner" provides a team approach with the needs. No one is boss, we are in this together!

To me, a "caregiver" is a professional person who has been trained/certified/educated to care for a person in need. It is usually a paid person who is not related or initially known to the family.
To me, a "carepartner" is a family member or close friend who has taken the responsibility of caring for a loved one. The two people are partnered with a relationship prior to an illness. The carepartner may or may not be paid.

For many years I have considered myself the caregiver because my loved one was at home with me. After it became too difficult to keep him at home due to his wandering off and being up at all hours, I finally decided I needed to place him in a memory care home. Luckily I found a wonderful small neighborhood home, called Goshen. There are only 6 residents including my spouse and he is the only male. The caregivers are specifically trained in dementia care and are certified. They are "true angels." So now I consider myself a caretaker. I visit him weekly and he is happy and safe. I don't have a real preference for the term, but I am just so thankful that there are special places for our loved ones when we can no longer manage them at home

I don’t think I’d heard the term “care partner” until this post, but have felt challenged to call myself the caregiver in the last few years.
My thoughts are similar to Price above. I was a caregiver for several years until my husband’s violent tendencies necessitated a move to LTC. Now I consider myself a care partner who works with the team to assist and support my husband in the best way.

I have also been a care partner for my mom for several years, as I never lived with my mom during her Alz journey, but found ways to support my mom & dad as they navigated her decline. My mom presently resides in same LTC as my husband and I am more involved now as her primary care partner.
