How to Say "to bite" in Spanish
The Spanish word for “to bite” is “morder” — A1 level. This is a very common word in everyday Spanish.

Examples
Ten cuidado, el perro puede morder si tiene miedo.
Be careful, the dog might bite if he is scared.
Siempre me muerdo las uñas cuando estoy nervioso.
I always bite my nails when I'm nervous.
Estos zapatos nuevos me muerden el talón.
These new shoes are pinching/biting my heel.
The 'O to UE' Change
When you emphasize the 'o' in the root, it changes to 'ue.' This happens in all present forms except 'nosotros' and 'vosotros.' For example: 'yo muerdo' but 'nosotros mordemos.'
Accidental Bites
When you bite yourself by accident (like your tongue), use the reflexive form 'morderse' + the body part: 'Me mordí la lengua' (I bit my tongue).
Keep it Regular in the Past
Mistake: “Yo muerdí ayer.”
Correction: Say 'Yo mordí ayer.' The 'o' only changes to 'ue' in the present tense, not the past.
