If two opposite sides are parallel, but the other two sides are not, then it is a trapezoidal figure, or simply, 'Trapezoid'. However, it is called 'trapezium' in British English.
The suffix "oid" has a definite meaning beyond mere language differences or understanding words fully. An "~oid" is a solid whose cross-section is a polygon.
I would be seriously concerned if a quadrilateral had more than two pairs of opposite sides parallel! A quadrilateral with two pairs of opposite sides parallel is a parallelogram.

A kite
a trapizoid
A trapezoid.
Then, the opposite sides are congruent.
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
