The Stems: 

The Stems Every triangle verb—in other words, all the verbs that use these endings—has an irregular stem. This means you will not be able to simply take the – ar , - er , and – ir off as you have done in the past. YOU MUST MEMORIZE THE STEM AS WELL AS THE ENDINGS.

These are the Stems Tener  tuv Poner  pus Saber  sup Estar  estuv Venir  vin Querer  quis Poder  pud Decir  dij Hacer  hic/z Traer  traj

If the stem ends in “j” drop the “ i ” in they. TRAJERON DIJERON
