Which of the following grammatical concepts is likely covered in the DLAB?

Verb conjugation is a fundamental grammatical concept often included in language assessments like the DLAB because it deals with how verbs change form based on factors such as tense, mood, or subject agreement. Mastery of verb conjugation is essential for constructing grammatically correct sentences in many languages. The understanding of how to effectively conjugate verbs can significantly impact a learner's ability to communicate clearly and accurately in another language. This concept is crucial as it forms the backbone of verb usage, helping learners express time-related nuances and actions regarding different subjects.

While article usage, pronunciation rules, and phrasal verbs are also important in language learning, they may not be prioritized to the same extent in a standardized test like the DLAB, which focuses more intensely on foundational structures such as verb forms that can affect overall language comprehension and communication skills.
