How to Say "to thaw" in Spanish
The Spanish word for “to thaw” is “derretir” — A2 level. This is a very common word in everyday Spanish.

Examples
El sol derrite la nieve muy rápido.
The sun melts the snow very quickly.
Tienes que derretir la mantequilla antes de añadirla a la mezcla.
You have to melt the butter before adding it to the mix.
El helado se derritió porque hacía mucho calor.
The ice cream melted because it was very hot.
The 'E' to 'I' Change
In many present tense forms and the third-person past tense, the middle 'e' changes to an 'i'. For example, 'yo derrito' (I melt) instead of 'derreto'.
Using 'Se' for Automatic Melting
If something melts on its own (like ice in a glass), we add 'se' to make it 'derretirse'. Example: 'El hielo se derrite'.
Forgetting the 'Se'
Mistake: “El hielo derrite.”
Correction: El hielo se derrite. (Use 'se' because the ice is performing the action on itself; otherwise, people might wonder what the ice is melting!)
