“Carers” as a noun refers to people who provide care and support to others, often those who are sick, elderly, or disabled. Some synonyms for “carers” are “caregivers”, “attendants”, and “nurses” (in a broader sense of providing care rather than just in a professional nursing capacity).
“Caregivers” is a commonly used synonym. For example, “The caregivers at the nursing home are dedicated to providing quality care.” This shows that caregivers, like carers, are focused on looking after the needs of others.
“Attendants” can also be used to describe those who attend to or take care of someone. “The patient had several attendants to help with daily tasks.” Here, attendants are performing similar functions to carers.
While “nurses” are often thought of in a professional medical context, in a broader sense they can be considered as a type of carer. “The nurses and other carers worked together to ensure the patient’s comfort.”
