Squashiness referes to the softness or compressibility of an object. Synonyms for this word includes pliability, malleability, flexibility, suppleness, sponginess, compressibility, elasticity, and resilience. Pliability is the capacity to bend and adapt without breaking or cracking. Malleability and flexibility are both similar words, emphasizing the ability to deform or reshape without fracturing. Suppleness refers to how easily something can be bent or moved. Sponginess suggests a texture that can be gently pressed down and then springs back to its original shape. Compressibility refers to the capacity for an item to be compressed and then rebound back to its original form. Elasticity and resilience both describe an object's ability to stretch and return to its original shape after being deformed.
