When describing something as "more ellipsoidal," there are several different synonyms that could be used to convey the same meaning. Some possible options might include "more oval," "more oblong," "more egg-shaped," or "more elongated." Each of these terms describes an object that is stretched out and tapered at the ends, similar to the shape of an ellipse. Other possible synonyms might include "more curved," "more rounded," or "more streamlined," depending on the precise shape and context of the object being described. Ultimately, the choice of synonym will depend on the speaker's intended emphasis and the specific qualities they wish to highlight.
