Questions & Answers about هو يرخي البرغي بمفك براغي.

Why is هو included if يرخي already tells us the subject is he?

Because هو is optional here.

In MSA, يرخي by itself already means he loosens / he is loosening, so Arabic does not need a separate subject pronoun the way English usually does. The sentence could simply be:

يرخي البرغي بمفك براغي.

Adding هو can:

• make the subject extra clear,
• add emphasis,
• sound natural if the speaker is contrasting him with someone else.

So هو is not wrong; it is just not strictly necessary.

What tense is يرخي?

يرخي is in the imperfect tense/form in Arabic.

In MSA, the imperfect can express:

• a present action: he is loosening
• a habitual action: he loosens
• sometimes a near future meaning, depending on context

So without extra context, يرخي can mean either he loosens or he is loosening.

What is the dictionary form of يرخي?

The dictionary form is أرخى.

So the pair is:

• أرخى = the past/basic dictionary form
• يرخي = the imperfect form
