IPA: //ˈspaɪ.kə//
KK: /ˈspaɪkə/
A type of bandage used to wrap a limb or digit in a way that keeps it still, often applied in a spiral or V-shape, or a bright star in the Virgo constellation.
The doctor used a spica bandage to support the patient's injured arm.
Spica comes from Latin 'spica' (meaning ear of grain or spike). The word refers to the spike or ear of a plant, particularly in the context of grains or grasses.
Think of 'spike' in 'spica' to remember that it refers to the ear of grain, as both words relate to the pointed shape of a grain spike.
