reiterate
to state or do over again or repeatedly sometimes with wearying effect
[M-W's Col. Dic.]

1: Is over joined only with do, or is it also joined with state? If it is joined with state, then the definition should be understood as: to state (over) or do over again or repeatedly...''.

2: Can over be eliminated from the above definition? What is the purpose of its use in the definition? The above definition makes perfect sense, at least to me, even without the over being in it.

3: What does the phrase with wearing effect mean?

"to state something or to do something [over and over again] or repeatedly, sometimes with the effect of making the listener feel exhausted"

It might have been simpler if the writer had simply kept to "to state or do something repeatedly".

"wearying effect" = makes you feel weary/tired.

The expression is over again. The over is not really needed, as you have already pointed out.

to state (over again) or do (over again) or state (repeatedly) or do (repeatedly) is the meaning.

over again implies once; repeatedly implies many times.

with wearying effect = with the result that a person becomes tired (weary) of the repetition.
