Peace All
Group 1: a, e , f, h, i, l, m, n, o, r, s, x
Group 2: b, c, d, g, j, k, p, q, t, u, v, w, y, z
Can you answer the question?
What characteristic in the Group 1 letters distinguishes them from the letters in Group 2?
Re: What trait do these letters share?
Come on people !!! 
Re: What trait do these letters share?
If i’m not wrong then the letters in group 1 have a vowel sound at the beginning. Whereas group 2 letter sounds are consonants.
Re: What trait do these letters share?
Yes … You are correct … As a result each of the vowel sounding letters would be preceded by “an” and the consonant sounding named letters would be preceded by “a” … Several consonants start with vowel sounds, but only “u” is the vowel that starts with a consonant sound. 
well done queserasera …
Re: What trait do these letters share?
Next question … How do groups 1, 2 and 3 differ from each other?
Group 1) a, b, d, j, k, p, q, t, v, z
Group 2) c, f, g, h, i, l, m, n, r, s, u, w, x, y
Group 3) e, o,
Re: What trait do these letters share?
Thanks.
I soooooooo want to answer the second ques but not sure if i’m correct. I think it has to do with the sounds again. Right or wrong? A simple Yes/ No/Sort of, would suffice. If yes, then i’m pretty sure i’ve cracked it; if not, then in the words of Poirot, have to use the little grey cells a bit more.
One more thing, are you absolutely, positively, 100% sure that the letter d is present in both groups 1 and 2?
Re: What trait do these letters share?
I only know this abc…
a for akmal
b for ball
c for catch
d for drop
Re: What trait do these letters share?
Aha … I think you are on to something … yes, the “d” was a typo in group 2.
Re: What trait do these letters share?
No no no no
A for apple
B for ball
C for cat
D for dog
E for elephant
Re: What trait do these letters share?
T for Typo
Re: What trait do these letters share?
I knew d wasn’t making sense in group 2.
Okay so here’s my answer… it has to do with phonics, or at least i think it does…
Group 1 letters: when sounding out these letters and also the words with these letters in it, you utter the first sound of the letter eg. a-> a-> apple, b-> ba-> ball emphasis being on the 1st sound and so on and so forth. I guess it also tends to predominantly retain the same sound/phonics, exception being when 2 or more letters are used in combo to get a different sound altogether as in ph:fa.
Group 2: Letters in this group have different or more than one phonics as compared to the sounds of the individual letters eg. c-> si-> cinder but also ka- cat, g-> jee-> giraffe but also ga-> get, h-> aich but when used starts with the sound ha, etc. Also quite a few of the letter sounds start with vowel sound that remains silent, and also have a second individual sound that forms the last part of the letter sound and is the only sound used for eg. f-> eff-> fa-> fox, m-> em->mm-> mango, x-> eks-> ks-> fox but also sounds as z as in xylem, xenophobia.
Group 3: not so sure about this group but this is how i see it.Vowels with same phonics as the letters. Or maybe has different vowel phonics when used in different words. Also half a dozen other explanations but they’re all muddled up in my head. 
Re: What trait do these letters share?
That is actually a very close assessment … It is to do with phonetics …
Group 1 letters when their names are spelt - the beginning sound is made with their own letter sounds. For example:
aey, bee, dee … etc … As you can see the names of the letters all start with their own letters themselves.
Group 2 letters are all named with beginning letter sounds that are made from other letters in the alphabet. For example:
c = see, f = eff, h = aitch … etc
Group 3 letters have names that the beginning sound cannot be made from any single letter in the alphabet.
e - contains a beginning sound in its name that is neither phonetically “e” nor phonetically “i” … rather double e is used to make the “ee” sound.
for o - it is not possible to use any one letter to make the sound for the beginning of this letter. It is neither “a” nor “e” nor “o” phonetically. The name of this letter starts strangely between the sounds “ur” and “a” … but is not exactly either sound and it transforms in to an “o” sound and then finishes off in a “ou” sound …
“aU-o-ou” - would be a good way to explain this …
