modélisent

Modélisent is the third-person plural present tense form of the French verb modéliser. It can be used in the present indicative, as in ils modélisent, meaning "they model" or "they are modeling," and it also appears in the present subjunctive (que ils modélisent), where the meaning is "that they model." As with other -er verbs, this form follows standard conjugation patterns, with the acute accent on the first syllable of the stem and the final -ent for the plural.

The verb modéliser derives from the noun modèle (model) and the -iser suffix that forms verbs meaning “to make into a model” or “to model.” Its core sense is to create, use, or refine a model to represent a system, phenomenon, or object. This includes producing mathematical, computational, physical, or conceptual representations that can be analyzed or used for prediction, design, or demonstration.

Usage in context ranges from scientific and mathematical modeling to computer graphics and design. For example, ils modélisent le climat pour prévoir les tendances futures. They model the climate to forecast future trends. In data analysis, on peut dire: ils modélisent les données pour construire un modèle prédictif. They model the data to build a predictive model. In architecture or product design, the term can also refer to creating scaled representations or simulations of forms and behaviors.

Related terms include le modèle (model), la modélisation (modeling), and le modéliste (model maker or fashion designer, depending on context). The form modélisent is widely used in contemporary French across scientific, technical, and applied disciplines.
