Hi Jim,
I am not sure I can answer your question completely.
So, I am just going to pull up a few examples, and make some observations…
In Roman 6:23, the phrase το χαρισμα- exists; “to charisma-”
That is a singular form, because the word before it is the evidence: eg:“to”
so that means the -ma ending does not make charisma plural, though you had a really good guess at the kind of change an ending would make…
A plural form is found in Roman 11:29; “ta charismat-a”. and doing some searching around, it is quite clear that “charisma” is a noun of the group ending in letters t,d,or theta. Charismat-ic, I think, is the proper English borrow word from Greek; as far as I am aware from English it means “spiritual gifts”.
So one word, basically is: “χαρισματ-??” (Charismat-??) and is a noun eg: a thing/gift.
This word is pretty much a new testament word, though I haven’t exhausively searched yet. It seems to be something Paul really likes, but very few others…
Here are some of the ways that word appears in Greek, using English letters.
to charisma (singular, drops the final t. as do most t,d,theta subject words.)
ta charismat-a (plural)
charismat-i (Dative),“i” suggests feminine: 1Cor1:6 – “to/concerning a gift”
charismat-wn (plural genitive) 1Cori 12:4 – “of gifts”
o charismat-os (singular genative) “o/os” suggests male. “of [a] gift” 1Timo 4:14.
the other word:
χαρι-σ-??? (Chari-s-???), when not followed by a verb ending, is also a noun. This is the normal word for grace or (as a verb/participle) a thanks/thanksgiving.
Charis is used by Paul in expressions like “Grace and peace of our Lord…”
and
“Thanks be to God”
The thing these two have in common is that they represent that which comes as a gift (grace) and that which is given back (a thanks or appreciation).
“Thus, If I have found grace in your eyes” – would imply appreciation, love of the true and beautiful, etc.
Charis to God – would mean, thanks be to God. etc.
I hope that helps; I am not sure if “charis” has a special theological meaning which is different from that of “charismat-”; But Paul’s near exclusive use of it would suggest that it is some kind of development of Church doctrine beyond the old testament.
