This is the 32nd most frequent Spanish word.
dijo
"She/he/it said" or "you (formal) said."
Here, 'dijo' once again represents the past tense action of stating or informing, attributed to 'él' (he).
¿Qué te dijo él sobre la reunión?
What did he tell you about the meeting?
In this example, 'dijo' is used to express the lack of communicative action in the past by any person.
Nadie me dijo que necesitábamos traer documentos.
Nobody told me that we needed to bring documents.
In this sentence, 'dijo' is the third-person singular preterite form of the verb 'decir', indicating that someone (she) communicated information in the past.
