tiksliais

Tiksliais is the instrumental plural form of the Lithuanian adjective tikslus, meaning precise or accurate. It is used to describe nouns in the instrumental case, typically to indicate that something is based on precision, such as data, measurements, or methods.

Common collocations include tiksliais duomenimis (based on precise data), tiksliais matavimais (by precise measurements), tiksliais skaičiavimais (with precise calculations), and tiksliais įrodymais (with precise evidence). This form commonly appears when referring to plural nouns in the instrumental case, for example duomenimis, matavimais, or įrodymais.

Grammar-wise, tiksliais agrees with the noun it modifies in number and case, and is one of several forms the adjective can take to match different nouns. It is most frequently encountered in formal or technical Lithuanian, especially in scientific writing, reports, and data-driven discourse.

See also: tikslus (the base adjective meaning precise), tikslumas (precision), tiksliai (adverb meaning precisely). The term emphasizes exactness in description, analysis, and reporting, and is part of a broader set of expressions used to convey methodological rigor in Lithuanian.
