Needle-like is a term used to describe a shape or object that resembles a slender, pointed needle. There are several synonyms for the word needle-like, including pointed, sharp, spiky, thorn-like, lanceolate, and acicular. Pointed and sharp are commonly used to describe objects that are tapered and sharp at the end. Spiky is used to describe objects that have several points or spikes protruding from them. Thorn-like is used to describe objects that are similar to the sharp, pointed protrusions on a thorn. Lanceolate and acicular are more technical terms used to describe shapes that are narrow and taper to a point, much like a lance or needle.
