An '''tagdo''' iyo an sadit na column nin [[likido]], napapalibotan nin biyo o haros biyo kan [[Free surface|free surfaces]]. An tagdo posibleng naporma kapah an likido natipon sa hababang puro kan tubo o iba pang surface boundary, nagpoprodusir nin nakabitay na tagdo na pig-aapod na [[pendant]] drop.
