Torukujulise

Torukujulise is the genitive singular form of the Estonian adjective torukujuline, meaning tubular or cylindrical. The base adjective torukujuline describes objects with a tube-like shape, such as pipes, vessels, or anatomical and engineered structures. Torukujulise appears when the modified noun is in the genitive case, and it is not a separate lexical entry but an inflected form of torukujuline.

Etymology and formation: The word is built from toru (tube) and kujuline (shaped, -like). The combination yields a generic meaning of “tube-shaped,” and Estonian uses inflection to align adjectives with their nouns. The -ise ending in torukujulise marks the genitive singular for adjectives in this stem class.

Grammar and usage: In Estonian, adjectives agree with the noun they modify in case and number. Torukujuline is the nominative form; torukujulise is used before a noun in the genitive singular, for example in noun phrases like torukujulise keha ehitus (“the structure of the tubular body”) or torukujulise toru omadused (properties of the tubular pipe). The form functions purely as a grammatical case-marked variant of the adjective, not as a separate lexical item.

Contexts: The term is common in technical, scientific, and descriptive writing where shapes are important, such as biology, engineering, architecture, and material science. It may appear in discussions of tubular organs, cylindrical components, or any situation describing tube-like geometry.

In summary, torukujulise is the genitive singular form of torukujuline and is used to describe a noun that is in the genitive case, conveying the idea of a tubular or cylindrical shape within a grammatically appropriate context.
