wriggle comes from Middle Low German or Middle Dutch wriggelen ('to wriggle'), a frequentative of wriggen ('to twist, turn'), of Proto-Germanic origin. The formation is best read through the historical forms named above, with the modern spelling preserving the outcome of that older derivational path. In modern use, the verb sense is "to twist and turn the body with quick writhing movements", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as wiggle and derivatives such as wriggler, wriggly, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Middle Dutch wriggelen, Proto-Germanic *wrigōną, which anchor the explanation in named linguistic material.
