A berry, typically green (classified as white), purple, red, or black, growing in clusters on a grapevine, eaten as fruit, and used in making wine. (Signing at age 4)
Phonological development study: The earliest video shows the baby Juli at 12 months (the beginning of a one-word stage) signing GRAPE.
It looks like a babble but it wasn't. In this context, she asked for it and waited for her mother to give her some more grapes. In the video, it seems that she was somehow conscious that it was on the top of the hand, not on the palm. Possibly self-corrected? Or, tried to learn to manipulate her hands (proximalization).
At age 4, the direction is cute. Her hand moves in the opposite direction from what most adults produce. But, if I recall right, I think there are a few adults signing that way as well (only on hand, not forearm). Phonological variation among adults. But, it's something I need to observe more.
