means Large woody perennial plants with a single main trunk that supports branches, leaves, and a spreading crown, typically living for many years.

from From Old English 'treow,' meaning both 'tree' and 'wood'—a word with deep Germanic roots and likely cousins across the Indo-European family, including Greek 'drys' (oak) and 'doru' (wood/spear). The same ancient root also gives us 'true' and 'trust,' carrying the old sense of something firm, steadfast, and reliably solid—as enduring as the timber itself.
