The phrase "It have started since" is grammatically incorrect. There are two main issues with this construction:
1. Subject-verb agreement: "It" is a singular subject and requires a singular verb form. The correct form should be "It has" instead of "It have."
2. Tense and aspect: The use of "since" typically requires the present perfect tense to indicate an action that started in the past and continues to the present.
A corrected version of this phrase could be:
"It has started since..."
However, even this corrected version is not commonly used in English. The verb "start" typically describes a single point in time, while "since" is used to indicate a period of time from a specific point in the past until now. Therefore, it's more natural to use verbs that describe ongoing actions or states with "since."
Some more appropriate and common constructions using "since" include:
1. "It has been... since..."
Example: It has been raining since yesterday.
2. "... has/have [verb in past participle] since..."
Example: We have lived here since 2010.
3. "Since [time/event], it has been..."
Example: Since the new policy was implemented, it has been easier to manage our workflow.
These constructions better capture the idea of an action or state that began at a specific point in the past and continues up to the present moment, which is the typical usage of "since" in English[1][2][3].
