In Spanish, Estudio can mean I study or I am studying. But to be clear that you mean I am studying (right now), you can say Estoy estudiando. For -er and -ir verbs, use -iendo (for example, Estoy comiendo).
hablar | hablando |
---|---|
comer | comiendo |
abrir | abriendo |
If there’s a vowel before -iendo, change the vowel to y.
