Answer
circle

The correct answer is circle — So the missing word is 'circle'.

Step-by-step solution

  1. Recall that a circle is the set of all points at the same distance from a center.
  2. This definition means the boundary is a single curved line.
  3. Hence a shape with only curved sides is called a circle.
  4. So the missing word is 'circle'.
Common mistake: Filling in 'ellipse' instead of 'circle'
