Trebladiga

Trebladiga is an adjective in Swedish that literally means “three-bladed” or “three-leafed.” It is formed from tre (three) and blad (blade or leaf) with the adjectival suffix -ig(-a). The form trebladiga is used to describe nouns that are plural or collectively regarded, while the corresponding singular forms are trebladig (masculine/neuter) and trebladiga when describing plural nouns.

In botanical usage, trebladiga describes plants whose leaves are divided into three leaflets or lobes. The term is common in descriptive plant keys and field notes, where a plant might be identified as having trebladiga leaflets or a trebladig leaf. In English, similar concepts are often expressed as trifoliolate or trifoliate, with trebladiga serving as the Swedish analogue.

Outside botany, the term can appear in technical or descriptive contexts to refer to objects with three blades or parts. For example, a propeller or turbine with three blades may be described as trebladig in Swedish, depending on the noun it modifies and the surrounding grammatical structure. The usage is generally limited to technical, descriptive, or stylistic writing rather than everyday conversation.

Related terms include tväbladig (two-bladed) and fyrbladig (four-bladed). The word is primarily found in Swedish-language technical vocabularies or dictionaries and is less common in general prose.
