Present Perfect + Since/For

Present Perfect + Since/For also works as Present Perfect Continuous. There are two ways to use “Present Perfect + Since/For” in place of Present Perfect Continuous.

1. When the action or event has started in the past and is still going in the present, we can use both Present Perfect + Since/For and Present Perfect Continuous.

“Present Perfect + Since/For” Definition

1. Started in Past and Still Going in Present = When the action, event, or activity has started in the past and it is still going in the present, we use “Present Perfect + Since/For” or “Present Perfect Continuous.” The work has started in the past but it has not stopped yet, it is still going. In these sentences, we mention the time. We use “Since/For” to Present Perfect also.

• We use “Since/For” to show that the work started at a specified time in the past. Without “Since & For,” it is hard to tell the starting point or period of time. Wherever we use “Since/For,” it defines that the work started at that point or period of time.

• We only use “Since” in perfect sentences like “Present Perfect, Present Perfect Continuous, Past Perfect, Past Perfect Continuous, Perfect Participles, Or Perfect Modals, etc.” But we can use “For” with any sentence.

Present Perfect Continuous Since/For Rules –

• Has + been + verb 1st form + ing = He, she, it, this, that, there, here, singular noun…
• Have + been + verb 1st form + ing = I, you, we, they, these, those, there, here, plural nouns…

Present Perfect Continuous + Since/For Format –

• Affirmative = Subject + has/have + been + verb 1st form + ing + (other words) + since/for + other words.
• Negative = Subject + has/have + not + been + verb 1st form + ing + (other words) + since/for + other words.
• Simple Interro = Has/have + subject + been + verb 1st form + ing + (other words) + since/for + other words?
• Simple Interro Negative = Has/have + subject + not + been + verb 1st form + ing + (other words) + since/for + other words?

• Interrogative Negative = Wh-family + has/have + subject + not + been + verb 1st form + ing + (other words) + since/for + other words?

But we can use Present Perfect Tense also with the same meaning sentences.
