British IPA: /ˈkjuː.bɪ.kəl/

Easy Pronunciation Guide: KYOO-bih-kəl

Syllables: cu-bi-cal (3 syllables)

Stress: The first syllable is stressed: CU: bical.

Beginner Pronunciation Tips

• Start with the sound “kyoo” like the beginning of the word “cube.”
• The middle sound is a short “bi” as in “big” without the final “g.”
• The ending sounds like “kul.”
• Do not pronounce it like “cube-ical” with four separate sounds. It is naturally pronounced as three syllables.

Meaning

Cubical is an adjective that means having the shape of a cube or relating to a cube-like form.

A cube has six equal square sides, so something described as cubical has a similar three-dimensional shape.

Examples of things that can be cubical:

• A cubical box
• A cubical building design
• A cubical container
• A cubical structure

The word does not usually describe a place or room. Instead, it describes the physical shape or appearance of something.

Describing Shapes

The most common use of cubical is to describe objects that look like cubes.

Example:

• The artist created a cubical sculpture from stone.

Sentence Function: Describes or modifies a noun.
