I'm curious about what ldc short for in JVM?

Question

ByteCode：ldc pushes a one-word constant onto the operand stack. ldc takes a single parameter, , which is the value to push.

Most of the bytecodes in JVM can figure out their name by the code description. However, the ldc, I don't see any clue.
