If we need to put the verb "arrive" into the 3 er person singular in the present form, we would say: "arriveS"
e.g: He arrives at any times every day. She arrives in a red car in the morning.
The inflictive -S makes reference to the 3p singular in present simple tense.
this modification will only occur with the subject he/ she and I, in the present simple tense.
