"Decidi" means "I decided" in English.
In this sentence, 'decidi' is used as the first-person singular past tense of the verb 'decidir,' indicating that the speaker made a decision in the past.
Eu decidi começar a estudar inglês.
I decided to start studying English.
Here, 'decidi' is seemingly used incorrectly since this is representing third-person singular past tense, which should be 'decidiu.' However, in colloquial use, speakers sometimes mistakenly use 'decidi'.

Maria decides to paint the living room walls light blue.
The word 'decidi' in this example acts to express a resolved action by the speaker regarding making a determinate choice about a subject matter.
