Mekanikajn

Mekanikajn is an Esperanto form of the adjective mekanika (mechanical) in the accusative plural. It is not a stand-alone noun; it functions to describe a plural noun that is the direct object of a verb or the target of an action.

In Esperanto, adjectives agree with the nouns they modify in both number and case. When the noun is plural and in the accusative case, the adjective takes the corresponding form, ending in -ajn. The noun itself also takes the accusative ending -n. For example, la mekanikajn partojn means “the mechanical parts” as the direct object, while la mekanikaj partoj refers to “the mechanical parts” in the subject or predicate position in the nominative plural.

Common usage examples include phrases like la mekanikajn partojn (the mechanical parts) and bezoni la mekanikajn ilojn (to need the mechanical tools). The form mek anikajn appears specifically when the emphasis is on the object being acted upon, rather than simply describing the parts in a non-objective role. The corresponding singular forms are mekanikan (accusative singular) and mekanika (nominative singular), with plural nominative forms mekanikaj and plural accusative forms mekanikajn.

Related terms include mekaniko (mechanics, the science) and mekanikaĵo (a mechanical thing or device). Understanding mekanikajn helps clarify constructive phrases in technical, engineering, and design contexts where multiple mechanical items are involved as objects of action.
