The Spanish word 'micrófono' comes from English 'microphone', which was formed from two Ancient Greek elements: 'mikros' (μικρός) meaning 'small' and 'phone' (φωνή) meaning 'sound' or 'voice'. The word was created to name the device that could capture and convert small sounds into electrical signals. The Spanish term maintains nearly the same spelling and identical meaning as its English source, just adapted to Spanish phonology and orthography with the addition of an accent mark.

Several common Spanish words share these Greek roots. Words with 'micro-' include 'microscopio' (microscope), 'microbio' (microbe), and 'microondas' (microwave). Words related to 'fono' include 'teléfono' (telephone), 'fonética' (phonetics), and 'sinfonía' (symphony). Understanding these connections can help you recognize and remember many Spanish technical and scientific terms.

The English cognate 'microphone' is obviously very close to the Spanish word. Other related English words using 'micro-' include 'microscope', 'microbe', and 'microwave'. The 'phone/phono' element appears in words like 'telephone', 'phonetics', 'symphony', and 'saxophone'. The similarity between these English and Spanish word pairs makes them easier to remember.
