Introduction
Love, compassion, and pity to Tonga and the city of Nuku'alofa.
There is disagreement whether Oceanic word: "to be fond of, to feel empathy for" is properly reconstructed as with an *l, making it a likely derivative of Austronesian *qalǝp: "to beckon, to wave", or with an *r, and thus presumably a separate root.
In Polynesian languages it becomes particularly confusing—first, almost complete merger of *r and *l, and second, the common practive in Polynesian languages of using "love, compassion" as a salutation. You could even imagine that the merger of "wave to" and "feel compassion for" drives the development of the salutation.
The resemblance to *qarop: "front, face", is most likely just an accident of the merger of Malayo-Polynesian *d and *r. Though there is some precedent for semantic shift between "face" and various emotions.
