When we talk about the word "branchlike", we usually refer to something that resembles the shape of a branch or parts that spread out in a similar way. Some synonyms of "branchlike" include "branching", "ramified", "tree-like", "diverging", "spreading", "forked" and "twiggy". All these words give the impression of something that has extended limbs or parts of similar shape. "Branching" and "ramified" are particularly useful when referring to structures that divide into smaller sections, while "tree-like" and "forked" are good for describing objects that split into multiple parts. So, if you're looking for alternatives to describe something that has a branch or stick-like shape, these words are great options.
