Purify or Be Purified

I don't know whether there exists a genre of dvar Torah called "Simchas-Torah Torah", similar to "Purim Torah".  If there isn't yet, I will create it:

During Hakafot today someone led the tzibbur in the song whose words come from the last mishna in Yoma:

אמר רבי עקיבא, אשריכם ישראל, לפני מי אתם מִטַּהרין, ומי מטהר אתכם, אביכם שבשמים, ....

ואומר, מקוה ישראל ה׳, מה מקוה מטהר את הטמאים, אף הקדוש ברוך הוא מטהר את ישראל.

If he sang מְטַהרין instead of מִטַּהרין, does he have to sing the song again?

זכור

After מעריב on כל נדרי night (hey, some people are always thinking דקדוק) someone asked me what determines when זְכֹר with a שוא is used as opposed to זָכוֹר with a קמץ. The catalyst for the question was likely זכר כי עפר אנחנו in אבינו מלכנו. It would seem that there is no actual difference in meaning between the two. One interesting clue that occurred to me was that we always find זָכוֹר followed by the word את, as in זכור את אשר עשה לך עמלק and זכור את יום השבת לקדשו. And it seems that זְכֹר is never followed by את, for example, זכר אל תשכח and זכר ימות עולם. Has anyone seen anything specific on this?

Reish

Interesting short article on pronunciation of the ר:

New Daf Yomi Blog

A little Weekly Shtikle blog cross-promotion. I recently started the new cycle of דף יומי and decided it would be nice to put down my thoughts and observations on the דף. And so, The Daily Leaf was born, joining the Weekly Shtikle family of blogs. There is even the occasional דקדוק piece. You can link to those straight with this link. Please check it out, read, enjoy, subscribe and comment.

Sunrise

A rather heated exchange has been brewing over at our sister-blog, AstroTorah, as to the exact proper grammatical term for sunrise. Is it נץ החמה or הנץ החמה? (Further, it is הָנֵץ or הֶנֵץ?) I figured we could settle this here. Discuss!
