discs

1. 1
   noun

   Plural of disc.

   An MRI showed that two of the discs in her lower back were damaged.

   Collectors still hunt for rare jazz discs at flea markets.

   Note

   The plural ranges from the spine to the record shelf: the cushions between vertebrae, vinyl records, flat round growths on a leaf, and flying discs, the generic name for a Frisbee. All of them count the same way. The spelling also belongs to the farming and aviation verb, so he discs the field and two discs in her back share a form but not a part of speech.

2. 2
   verb

   Third-person singular simple present of disc.

   He discs the stubble under each fall so it breaks down over the winter.

   Once the propeller discs on touchdown, the added drag slows the aircraft quickly.

   Note

   Two trades keep this verb in use. A farmer discs a field by drawing a disc harrow over it, turning stubble under; on an aircraft, a propeller discs when its blades swing to zero pitch, face-on to the oncoming air, so that they drag hard and slow the plane. The farming verb takes the ground as its object, while the propeller one usually stands alone.
