When plaintiff goes in appeal then he is called plainticf appellant.

The term 'appellant' means a person who is appealing a court decision. So if someone loses a case at a tribunal and appeals to a higher court they are said to be an appellant.

The cross-appellant in a case is the person who files a cross-appeal to counter an appeal already filed by the original appellant. Usually, the original appellant would be the party which lost the case in trial court, and would be asking the Appeals court to overturn the trial court verdict. A cross-appellant is usually the party which received a verdict partially in their favor at trial, and is counter-appealing some aspect of the trial court's verdict to the Appeals court. A 'defendant-cross-appellant' is means that the party which was the defendant in the trial court, is now the cross-appellant in Appeals court.
