How to Say "to ingest" in Spanish
The Spanish word for “to ingest” is “ingerir” — B2 level.

The Stem Change
This verb has a 'double life' for the letter 'e'. In most present tense forms, the 'e' becomes 'ie' (like 'ingiero'). However, in the 'nosotros' form of the special mood (subjunctive) and the third-person past tense, it changes to just 'i' (like 'ingirieron').
Don't use it at dinner
Even though it means 'to eat' or 'to drink,' using 'ingerir' at a restaurant would sound like you are a robot or a doctor. Stick to 'comer' or 'beber' for daily life.
Forgetting the 'i' change
Mistake: “Ellos ingerieron mucha agua.”
Correction: Ellos ingirieron mucha agua. (In the past tense for 'they', the 'e' must change to an 'i').
