Definisci

Definisci is an Italian verb form commonly encountered in written and spoken language. It is the second-person singular form of the verb definire in the present indicative, meaning you define. In many contexts it also functions as the informal imperative command to someone you address as “tu,” telling them to define something. Because the spelling of the present indicative form for the second person singular matches the imperative in everyday use, context and punctuation typically clarify the mood.

Etymology and grammar: definire comes from Latin definire, meaning to set a boundary or to define. In the present tense, the conjugation for the singular forms is: io definisco, tu definisci, lui/lei definisce. The form definisci is therefore tied to the root defin- and the standard -ire verb pattern with the -isci ending in the second person singular.

Usage and examples: definisci is widely used in instructional, academic, and technical writing. Examples include phrases such as “Definisci i termini del problema” (Define the terms of the problem) or “Definisci il perimetro entro cui operare.” When used as an order, it appears as “Definisci i parametri” or simply “Definisci!” in a direct command, with punctuation signaling the imperative mood.

Notes: Definisci is not a proper noun or a distinct concept beyond its role as a verb form. In English, its equivalents are “you define” (present indicative) and “define” (imperative), with the exact meaning determined by context and punctuation.
