Etymology: The plural "tentacula" is the Latin-style form of "tentaculum", a word that English took from New Latin, the scientific Latin used by naturalists from the early modern period onward. The Latin base is "tentare", meaning "to feel" or "to try", the same root that gives English "tentative". A feeler is literally what the word describes: the organ an animal uses to touch and probe its surroundings before committing to a movement. The singular "tentaculum" was coined as a technical term, so it carries the scientific sense of a slender, flexible appendage, and the plural follows the Latin pattern of ending in "-a". English speakers more often use the anglicised form "tentacle", which is a doublet of the same word, meaning the two came into English by different routes from one source.
