Variant of 穎

It is another written form of 穎, not a new word.

In ancient Chinese oracle-bone writing—inscriptions on bone and turtle shell—early forms of 穎 are read as a grain stalk with multiple ears. Its literal sense is the stalk or pointed end of a grain. Mandarin reads 穎 as yǐng; Japanese as ei, Korean as yeong, and its Vietnamese Hán-Việt reading is dĩnh.

In later Chinese writing, 穎 also came to praise standout talent. The idiom 錐處囊中，穎脫而出 pictures an awl’s point pushing through its bag: ability that cannot stay hidden.
