from The Century Dictionary.
- To grope.
Sorry, no etymologies found.
In all which matters there were many obvious occasions for those little attentions which are much valued by persons in like situations; and Tom was not sorry that the boys had voted the whole preparations a bore, and had gone off to the brook to 'gropple' in the bank for crayfish till the shooting began.
O'BRIEN: So it's halfway between snow and sleet is gropple, is it?
