Morphology

knotweed = knot + weed (semi-transparent) = knot + weed

The parts 'knot' and 'weed' are semantically clear (indicating a kind of weed), but the compound names a specific plant (often an invasive species) so the full meaning is more specific than the simple parts.

Etymology

The word knotweed comes from the parts knot and weed, so picture a wild plant with 'knots' in its stems and roots. Those tight, knot-like roots are very hard to pull out, which is why knotweed often spreads quickly and can damage gardens and buildings.
