please tell me which one is the right sentence ,''can you do us some favour?" or "can you do us a favour?".
"Your presence is always there and love" is not a correct sentence. You might write "you and your love are always here for me."
It can be correct to say you are always welcomes. It is correct when finished with "in my home or at my place of business."
it is correct
It is 'you are always' and not 'you always' in a sentence for the purposes of correct grammar.
No, they are always incorrect.
Most of the time, but people are able to edit Wiki so it is not always correct, because people are not always correct.
a - he always does it
NO
A number must always be followed by it's correct unit.
Real small
Yes, the sentence "She does not always complete her homework" is correct.
Your presence is always there for me is technically a correct sentence. It might sound better if written "you are always there for me." The addition of "your presence" is redundant.
