WHOLE CHARACTER
累
tired; weary; to make tired; to strain
累 changes tone with meaning: lèi is tired, lěi is to pile up or accumulate, and léi survives in set words like 累赘.
The header marks 会意, while the detailed entry ties the léi reading to 畾 as the sound side over 糸 (the older 纍 stacked three 田); the lěi reading has a separate piled-clod associative account. The modern form is shown as a visual split, with reading-specific history kept limited.
