laboratorajn

Laboratorajn is an Esperanto adjective form used to describe plural nouns in the accusative case that relate to a laboratory. It represents the accusative plural variant of the lab-related adjective and is typically found before a plural noun such as ilojn (tools) or rimedojn (means).

In Esperanto grammar, adjectives agree with the nouns they modify in number and case. The accusative plural ending for adjectives is -ajn, so a phrase like la laboratorajn ilojn means “the laboratory tools” where both the noun ilojn and the adjective laboratorajn are in the accusative plural. This form is common in technical or instructional texts when specifying equipment or resources associated with a laboratory.

Examples:

- Li uzis la laboratorajn ilojn. (He used the laboratory tools.)

- La laboristoj altiris la laboratorajn rimedojn por la eksperimento. (The workers used the laboratory means/tools for the experiment.)

Laboratorajn, therefore, is not a stand-alone noun but a grammatical form used to express “laboratory-” in the plural accusative context, enabling precise description of laboratory-related objects within sentences.
