A shoulder to tip of opposite outstretched hand, length of log, either cut from a log or marked for that length by a notch, geppang, but not yet cut off.
Ināan'uy ohay nab'uh din āyiw'u ti madamot an adīa' pa'addon.
I (cut) off one shoulder to tip of opposite outstretched hand length of log from my wood because it was heavy and I couldn't carry it.
A single length of log, when split, is the correct length to fit in a drying rack, hugūhug, over a fireplace.
