Oops

I very often find myself focusing very closely on possible little mistakes that might go unnoticed and sometimes, the bigger mistakes fly over my ahead. Such was the case one פרשת פרה when I missed a biggy. Fortunately, it was in the הפטרה. In (יחזקאל ל"ו:ל), instead of פרי העץ, the בעל קריאה said פרי הארץ!! I heard murmurings and I knew I had missed something but I just wasn't sure what it was so I couldn't very well correct it.

I joked with people afterwards that perhaps it is not such a serious mistake. After all, if you make a בורא פרי האדמה on an apple, you are יוצא, right? It is still אדר.

Let your Soul not be Desolate

Although mistakes in the הפטרה might not be as serious, they tend to be more prevalent since the reader of the הפטרה tends to be less of a seasoned lainer (depending on the shul.) Unfortunately, there was one year I heard this done completely wrong every time. In the הפטרה of פרשת פרה, towards the end, there are numerous instances of the word נְּשַׁמָּה, meaning desolate. If it is mispronounced נְּשָׁמָה it refers to the soul. Two words, nearly indistinguishably similar whose meanings couldn't be further apart. It would be advisable, if you know who will be laining the הפטרה, to alert them to this in advance. Fortunately, our shul has acquired קלף's for all the הפטרות and now only actual בעלי קריאה lain it.

As MG points out in the comments - for those who are particular about pronouncing a דגש חזק - the דגש in the מ is also an important distinction between the two words.
