'dome-shaped' originates from the word 'dome,' which comes from the Latin word 'domus,' meaning 'house.' The suffix '-shaped' is used to indicate the form or appearance of something.

'dome' changed from the Latin word 'domus' to the Old French word 'dome,' eventually becoming the modern English word 'dome.'

Initially, 'dome' referred to a 'house' or 'building,' but over time it evolved to describe a rounded, vaulted structure.
