Disclaimer: I am not a linguistics this could be very inefficient idk 😐
So since the symbols for Gnommish are directly interchangeable with English characters I used some existing given words such as Darvit and kadalun to do ✨
a = ùh, b = d, c = heh, d = fuh, e = ugh, f = m, g = t, h = n (made with back of throat), i = ó, j = cr, k = lo, l = f, m = i, n = r, o = ay, p = s, q = w, r = l, s = oo, t = g, u = uh, v = th, w = are, x = v, y = un, z = Z
Upper Case (no vowels and * means explosive letter such as puh)
B = da*, C = éh, D = fúh, F = Ka*, G = ti, H = pr, J = Rah*, K = beh, L = ti, M = ee, N = ehm*, P = feh, Q = qi (made with back of throat), R = dia, S = puh*, W = nuh, X = zee, Y= see, Z = ks, T = tag.
In terms of grammar like how explosive upper case lettets have '-' seperating them from the rest of the word and if some non capital letters have tones and barely any upper case letters have tones.
If there are any inconsistencies or if you want examples of putting words together ask.
If not have fun using a very inefficient Gnommish dialect I guess.
