'antenna-shaped' originates from the word 'antenna,' which comes from Latin 'antenna,' meaning 'sail yard.' The suffix '-shaped' is derived from Old English 'sceap,' meaning 'form or shape.'

'antenna' was borrowed from Latin 'antenna,' and the suffix '-shaped' was added in modern English to describe objects resembling an antenna.

Initially, 'antenna' referred to a 'sail yard,' but over time it evolved to describe the sensory appendages of insects and other animals, and 'antenna-shaped' now describes objects resembling these appendages.
