An auxiliary verb, also known as a helping verb, is a verb that is used with a main verb to form a verb phrase. It helps to express the tense, mood, or voice of the main verb. Common auxiliary verbs include "be," "have," and "do." A main verb, also known as a lexical verb, is the primary verb in a sentence that carries the main meaning or action. It is the verb that is not preceded by an auxiliary verb in a verb phrase. Main verbs can express actions, states of being, or occurrences. **

'Before the verb' refers to the placement of adverbs in a sentence. Adverbs are words that modify verbs, adjectives, or other adverbs. When an adverb is placed before the verb in a sentence, it typically provides information about how the action is being performed. For example, in the sentence "She quickly ran to the store," the adverb "quickly" is placed before the verb "ran" to describe how she performed the action of running. **

The personal form of the auxiliary verb is the form that changes based on the subject of the sentence. For example, in the present tense, the personal forms of the auxiliary verb "to be" are "am" for the first person singular (I), "are" for the second person singular and plural (you), and "is" for the third person singular (he/she/it). These forms change to match the subject of the sentence and indicate who is performing the action. **
