The spelling of the word "arm legs" is incorrect. The correct spelling is "arms and legs". The word "arms" is pronounced /ɑːmz/ in IPA phonetic transcription, with a long "a" sound and a voiced "s". The word "legs" is pronounced /lɛɡz/ with a short "e" sound and a voiced "g". Together, they form a compound noun that refers to the limbs of the body used for movement and support. It is important to spell words correctly to ensure clear communication and understanding.
