付き添い also means attending or accompanying someone, but it often implies a more formal or temporary escort, such as a hospital attendant or a chaperone, whereas 付きっきり emphasizes continuous, uninterrupted presence.
Derived from the verb 付く (つく, 'to attach') in its continuative form 付き, combined with きり (from 切る, 'to cut off'), indicating a state of being continuously attached or present. The geminated form 付きっきり is a common emphatic variant.
