Tips

usage
has three readings. lèi (this entry) = tired / to tire — by far the most common in modern speech (, 心累). lěi = to accumulate / implicate (积累, 拖累). léi = piled-up / a burden, mostly literary (累累, 累赘). Tap the pinyin on each compound to see which reading it uses.
usage
The X+死了 pattern is a hyperbolic intensifier — 累死了 (dead tired), 热死了 (boiling hot), 饿死了 (starving), 气死了 (furious). Everyday colloquial, not literal.

Components

radical
silk thread
Bottom indexing silk radical (Kangxi #120) — pictograph of twisted silk strands. Anchors in the textile / bundling family alongside , , . Bundles tied with silk thread = piling things up = the burden of a heavy load = 'tired.'
semantic
tián
field (here: bundle of cocoons)
Top 5 strokes — graphically (field), but historically a stack of silk cocoons. The original depicted three cocoons above a thread — the picture of bundling silk together. Modern simplification reduced the three to one. Read this slot as 'a piled bundle' rather than 'field.'
