Split infinitives occur when additional words are included between to and the verb in an infinitive. Many readers find a single adverb splitting the infinitive to be acceptable, but this practice should be avoided in formal writing.
When he was 11 years old, Itachi was also under orders from his father to enroll in the Anbu half a year later. Itachi was praised highly by Fugaku, who spent most of his time grooming Itachi to inherit the title of leader of the Uchiha, and hence inadvertently neglected his younger son.
When Fugaku asked him if he knew of their clan meeting, Itachi told him no. Fugaku told Itachi that the next clan meeting is in three days, however Itachi told him that he has a mission. While walking away, Itachi was told by Fugaku not to run away from his Uchiha destiny, and told to meet him after their clan meeting.
