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

Examples

She always smiles when she sees me.
¿Por qué no sonreíste en la foto?
Why didn't you smile in the picture?
El bebé está sonriendo mientras duerme.
The baby is smiling while sleeping.
The Accent is Essential
In the present tense, you must place an accent on the 'i' (sonrío, sonríes, sonríe, sonríen). This separates the vowels and ensures you pronounce the 'ee' sound strongly, making it an irregular verb.
The Hidden 'E' to 'I' Change
In the third-person preterite (past tense) and the subjunctive forms, the 'e' in the stem changes to an 'i' (e.g., él sonrió, nosotros sonriamos). This is a common pattern for many -ir verbs.
Forgetting the Accent
Mistake: “Yo sonrio (missing accent)”
Correction: Yo sonrío. Without the accent, the word looks regular, but sounds wrong. The accent is mandatory for this verb.
Incorrect Gerund
Mistake: “El está sonreiendo.”
Correction: El está sonriendo. When forming the continuous action (-ing form), the 'e' in the stem changes to 'i' (sonriendo).
