My gommorah reads k'tsira dome d'charisha ...

(In the future, please copy the text in question into your correspondence, to avoid confusion.)
We wrote in the Outlines to Makos 8:3:i:2 the following: "R. Yishmael says, (the verse forbids plowing and reaping on Shabbos -) just as plowing is Reshus, also reaping - this excludes reaping the Omer, which is a Mitzvah, it is permitted on Shabbos."
This is the translation of the line in the Gemara, "Ketzirah Dumya d'Charisha." This means, "The Ketzirah of the verse is similar to the Charishah mentioned in the verse." Just as the Charishah of the verse is certainly a Charishah of Reshus, so, too, the Ketzirah of the verse is referring only to a Ketzirah that is a Reshus.
If this does not answer your question, please write back and try to be more clear.
