The phrase 'dicit se venire' translates to 'he/she says that he/she is coming' and illustrates the use of reflexive pronouns in Latin. In this expression, the reflexive pronoun 'se' refers back to the subject of the verb, emphasizing the action is being performed by the same person who is the subject. This construction is crucial for understanding indirect statements, where a speaker reports what someone else has said while maintaining clarity about who is performing the action.
