"CATAINJFUNEL or CATAIN?FUNE" I meant CATAINI?UNE
So indeed it seemed likely to be F but it does not quite match and so its more of a V than the similar shape in the Engineer Hieroglyphs.
The Problem with Engineer Writing is that on a lot of the works, as far as where it appears we cant make out where the Spaces are.
So the Cat had the Hat is (sothecathadthehat) but you imagine if English was not your first Language and you had to figure where the spaces between words are!
I think a lot of Engineer Writing Once you can Translate it to the English Alphabet... you have to then figure where the spaces are and then Translate the Words from Latin and Greek to get English.
So i think its a case of how many Spaces are between CATAINJFUNEL are we looking at CATAIN as first word? CATA... then.. INJ and once we figure out how this splits into words we then run them via Greek and Latin Translations to get what we want.
So in Reverse Order we take CURSE into Latin to get MALEDICTUM
and then we Translate that to Engineer. But Sometimes its Translated to Greek and so the Word would be ΚΑΤΑΡΑ
Thus the Engineer for CURSE would be either..

Thats how my Study worked it out... a lot depends IF it indeed is a case of the Engineer Alphabet = a Word that is either Latin or Greek (i think they mix and match it) then Translate the Greek/Latin to English and see if it makes sense..
They KEY is knowing where the Words are Spaced Out... because well

Would make no Sense to those who dont understand Greek and could not even guess the Spaces.
