impersonal verb वाक्य

An impersonal verb is different from a defective verb in that with an impersonal verb, only one possible syntactical subject is meaningful ( either expressed or not ), whereas with a defective verb, certain choices of subject might not be grammatically possible, because the verb does not have a complete conjugation.

In Palestian Arabic, " Id-dunya ti-shti " translates to " It ( the world ) is raining " and uses a non-impersonal verb . " Vreme je sun ano ", which means " the weather is sunny ", is a common Serbian construction that uses a ( non-impersonal ) adverb rather than a verb.
