The term 'It May Be Blowing In The Wind' can be summarized by two crossword solutions: SPORE (5 letters) and REED (4 letters). SPORE is a microscopic reproductive body produced by certain plants, fungi, and protozoans. It is capable of developing into a new individual without sexual fusion. REED is a tall, slender-leaved grass of the genus Phragmites, which grows in dense stands in marshes and other wet areas. Both SPORE and REED are often found blowing in the wind, hence the phrase.
