Incorrect usage

A few weeks ago a renowned solicitor as well as the editor of a Parsi weekly wrote "Atha zamyad yatha afrinami” at the end of their article and column respectively. This is incorrect. The proper version should be "Atha jamyaat yatha aafrinaami” which means "so may it come (happen) as I bless it.”
It should be noted that Zamyad is the name of a Yazad, whereas jamyaat means tense or mood. Grammatically it is potential or benediction mood parasmaipada third person singular of root jam or jas which means "to come.”
Whenever words from prayers are to be quoted, the prayer book should be referred to first. The print media is accessed by thousands of people and if something incorrect is printed, people are misinformed. NARIMAN A. MODY

London based independent researcher on Zoroastrianism Farrokh Vajifdar explains:
Your correspondent is quite right in the essentials of his plaint. One has despairingly endured the nonsensical Zamyad in this valedictory context, and protested against it to no avail.
There also persist deviant expressions as Tandorasti (for Tan darosti — "Good health!”; Ashobederji (all in one gasp, for the exhortative Asho be! Der zi! — "Be righteous! Live long!”); the newly fashionable Ushtate (for Ushta te! – "Hail!,” "Hello (to you)!” (!), even "Hi!” for the trendy; and the acutely irritating Banamekhooda (Ba nam-e Khoda — "In the Lord’s name” — most often when something dubious is to be proposed.
Zam is the presiding genius or guardian spirit of the earth (as sacred element). As Yazad or worshipful entity the name underlays the first part of the much-studied Zam Yazad or Zamyad / "Jamyad” Yasht. That such evident disrespect is paid to this cardinal environmental being is beyond my comprehension.
The verbal root in Avestan is gam; the Sanskrit has GAM; gachati. The basic meaning is "to come” with several auxiliaries as "attain to,” "arrive in,” "produce,” "acquire a quality of.” With certain prefixes — upa, paiti, pairi — it evokes a profound and extensive range of ideas.
One has only to think of Zarathushtra’s use of gam in the first Ushtavaiti (Ys.43) where it occurs precisely in certain verses as pairi.jasat, only to baffle the student with translation alternatives. For the curious, it must be divulged that the sage owed his inspiration and esoteric knowledge of Mazda to the prime Ahuric aspect of Vohu Mana — the divinely conferred aspect of "good mind” in which all enlightened humanity can share.
On the point of exactly edited prayer books, may s/he be referred to the article "Promoting Prayer” (Parsiana, August 7, 2015). Where Atha jamyat, yatha afrinami started off, we end with a heartfelt Edon baad; edon-taraz baad — "May it be thus; may it ever be thus.”
