What does wiggler mean?
A wiggler is someone or something that wiggles—that is, moves repeatedly in a small, irregular, side-to-side fashion. The word is most often used informally for a restless person who wriggles, twists, or refuses to stay still, usually with a mildly teasing or exasperated tone: “That child is quite a wiggler.” It can also describe a physical object or component that moves slightly, such as a loose wire or small moving part. In such contexts, “wiggler” is neutral and suggests movement that may be intentional, mechanical, or caused by being out of position. The distinction from “wriggler” is mainly one of emphasis: a wiggler typically makes lighter, oscillating movements, while a wriggler twists or writhes more vigorously. The word is a familiar English derivative of “wiggle,” combining the base verb with the suffix “-er,” which marks an agent or instrument. It is especially useful when the movement itself is the noteworthy feature, whether the subject is a person, an animal, or an object.

"The wiggler kept escaping from beneath the blanket."
"The baby otter was an energetic wiggler and soon climbed out of the basket."
"She pressed the loose wiggler back into its socket."
The regular plural retains both l-sounds and is used for people, objects, or components that wiggle.
"Several wigglers were hiding among the seaweed."
The clue is in the ending: a wiggler is simply someone—or something—given to wiggling.
