Etymology
The word 'palp' is a direct borrowing from the Latin palpus, meaning 'the palm of the hand, a caress, or a feeler'. This Latin term is derived from the verb palpare, 'to touch softly, to stroke', which itself has uncertain but likely Proto-Indo-European origins related to the concept of touching or feeling. The semantic journey moved from the general act of gentle touch to specifically denote the tactile, finger-like appendages of invertebrates. As a simplex loanword, its modern biological meaning retains the core logic of its Latin source: a soft, feeling organ.
