rain tree
C2Formal, Technical/Botanical
Definition
Meaning
A large tropical tree (genus Samanea, especially Samanea saman) with a wide-spreading canopy of feathery leaves that often folds up at night or in cloudy weather, creating an effect resembling rain as moisture drips from its leaves.
Any of several tropical trees, particularly Samanea saman (also called monkeypod), noted for their expansive, umbrella-like canopy and the phenomenon where droplets (from condensation or secretions from insects) fall from the leaves. It is often planted for shade in parks and along streets.
Linguistics
Semantic Notes
The term refers specifically to a type of tree, not a general tree in the rain. The "rain" refers to the dripping phenomenon. It's a compound noun treated as a single lexical unit.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like 'дождевое дерево' which sounds unnatural. The established translation is 'дождевое дерево' (as a fixed term) or more precisely 'саман' or 'обезьянье дерево'.
- Do not confuse with 'тропическое дерево' (tropical tree) which is a broader category.
Common Mistakes
- Using 'rain tree' to describe any tree in the rain. *'We sheltered from the storm under a rain tree.' (Incorrect unless it's the specific species).
- Spelling as two unhyphenated words 'rain tree' is standard, but sometimes seen hyphenated 'rain-tree' in older texts.

FAQ
Frequently Asked Questions
Yes, 'monkeypod' is a common synonym for the rain tree (Samanea saman), particularly in American English and in Hawaii.
It's named for the phenomenon where moisture (from condensation, or secretions from insects like spittlebugs) drips from its leaves, creating a light rain-like effect under the canopy.
Only if you are referring to that specific type of tree. In general contexts, saying 'a big shady tree' is more common unless the species is relevant.
They are native to tropical Americas but have been introduced and are now common in many tropical regions worldwide, including Southeast Asia and the Pacific Islands, often as ornamental shade trees.
