The Chinese word 空降 is formed by directly combining the character 空 (kōng), meaning 'sky' or 'air', with 降 (jiàng), meaning 'to descend' or 'to drop'. This combination results in a compound word where 空 modifies 降 to specify that the descent occurs from the air, thus giving the term its meaning of 'airborne' or 'parachute drop'.
