Abstract (The Variation -esc/-ø at Present Indicative of 4th Conjugation Romanian Verbs. A Normative Analysis based on DOOM3 (The Orthographic, Orthoepic and Morphologic Dictionary of the Romanian Language) This paper aims to investigate the conjugation tendencies of fourth-conjugation verbs in contemporary Romanian, focusing on establishing the proportions between verbs that use the -esc augment (weak present), those that conjugate without the augment (strong present), and those that display variation between the two patterns. Based on an inventory of 729 verbs extracted from DOOM3, the analysis identifies clear markers in line with the current linguistic standard: 510 verbs use the augment -esc, 188 verbs conjugate without the augment, and 31 verbs show variation between the two forms. The purpose of this study is not only to detect current flexional trends but also to formulate coherent and systematic lists, aligned with recent normative codifications. The research examines in detail the morphological behavior of verbs based on their infinitive endings (-ui, -ăi, -âi, -ări, -ăni) and tracks how these forms either conform to or deviate from traditional paradigms. By combining quantitative analysis with normative observations, the study contributes to refining the classification of fourth-conjugation verbs and enhancing the understanding of morphological evolution processes in contemporary Romanian.
