Etymology: "Undergrowing" is the present participle of "undergrow", which is built from the prefix "under-" and the verb "grow". The combination is transparent: "under-" means beneath or below, and "grow" means to increase in size or develop, so the verb describes something that develops beneath something else. Its use as an adjective, meaning growing underneath something, follows the same logic, as in an undergrowing layer of plants beneath a forest canopy. The pattern is a productive one in English. "Undergrow" belongs to a family of verbs with "under-" that describe a lower or subordinate action, such as "undercut" or "underlie", and the sense of growth beneath or below a larger body is the plain literal meaning carried over into the verb. The word is a straightforward compound with no surprising shift in meaning.
