In anatomy, an areola (/əˈriːələ/) is any small circular area on the body coloured differently from the surrounding tissue. The term is most commonly used to describe the pigmented area on the human breast around the nipple (areola mammae) but it can also be used to describe other small circular areas such as the inflamed region surrounding a pimple.
The plural of "areola", is "areolæ"/"areolae", which is pronounced /əˈriːəliː/ or /əˈriːəlaɪ/. "Areola" is the diminutive of Latin area, "open place".
