Final answer:
The present indefinite tense, also known as the simple present tense, is used to talk about actions that happen regularly or facts that are true in general. To form the present indefinite tense, use the base form of the verb without any changes. In the given sentence, the correct form of the verb is 'speaks' in the present indefinite tense.
Step-by-step explanation:
In English, the form of the verb changes to indicate whether an action is happening currently or has happened already. These changes are called verb tenses. The present indefinite tense, also known as the simple present tense, is used to talk about actions that happen regularly or facts that are true in general.
To form the present indefinite tense, use the base form of the verb (also known as the infinitive) without any changes. For example, in the sentence "I speak English," the verb 'speak' is in the present indefinite tense.
So, in the given sentence "For some time not a word (speak) change present indefinite?", the correct form of the verb is 'speaks' in the present indefinite tense. The corrected sentence would be "For some time not a word speaks."
