plate, to have a lot/enough on one's(redirected from to have a lot/enough on one's plate)
have a lot on one's plate
Also, have too much on one's plate. Have a great deal (or too much) to cope with, as in What with the new baby and the new house, they have a lot on their plate, or I can't take that on now; I've got too much on my plate already. This expression transfers a loaded or overloaded dinner plate to other activities. [First half of 1900s]
plate, to have a lot/enough on one's
To have more than enough to worry about or cope with. This term originated in the 1920s and transferred the image of an overcrowded dinner plate to a very full agenda. R. Simons used it in Houseboat Killing (1959): “I’ll leave you at it. I’ve got plenty on my plate at the moment.” The synonymous my plate is full (or to have a full plate) date from the same period.
