trascurabili

Trascurabili is an Italian adjective used to describe quantities, effects, or factors that can be ignored in an analysis because their size is negligible compared to the dominant terms. The term is the plural form of trascurabile and is commonly paired with nouns such as variabili, elementi, o termini.

The word derives from trascurare, meaning to neglect, with the suffix -abile indicating capability. In scientific and technical writing, trascurabili characterize contributions whose impact falls below the precision or relevance of the model under consideration. The choice of trascurabili is often conditional, stating that something is negligible “ai fini dell’analisi” or within the given order of magnitude.

In practice, writers use trascurabili to simplify models and calculations. For example, a force component may be described as trascurabile at high speeds, or a term in a series may be treated as trascurabile beyond a certain threshold. This concept helps to focus on the dominant terms while clearly indicating the assumption of approximation.

Nuance: trascurabili emphasizes the practical insignificance within a particular context, whereas synonyms like irrilevanti or non rilevanti may carry a stronger or more absolute meaning. Correct use depends on specifying the condition under which the negligible nature holds, such as measurement precision or model goals.
