The Spanish word 'anemómetro' (wind meter) comes from combining two Ancient Greek words: 'ἄνεμος' (anemos) meaning 'wind' and 'μέτρον' (metron) meaning 'measure'. These Greek elements evolved into the Spanish combining forms 'anemo-' (relating to wind) and '-metro' (measurement), which were joined together to create this compound word referring to an instrument that measures wind speed.

Other Spanish words containing '-metro' are common and relatively simple to learn, such as 'termómetro' (thermometer), 'kilómetro' (kilometer), and 'barómetro' (barometer). All these words follow the same pattern of measuring something, with '-metro' indicating the measurement aspect.

English speakers might recognize this word's connection to 'anemone' (the flower and sea creature), which also comes from Greek 'anemos' (wind) - the flower was so named because its delicate petals easily blow in the wind. The '-meter' part is extremely common in English, appearing in words like 'meter', 'thermometer', and 'speedometer', all derived from the same Greek 'metron'.
