No English word is allowed to have an <i+i> letter string.
The reason for this spelling law is that in old script <ii> would be easily confused with the letter <u>.
In a compound word, you may not drop any letters from either base in order to join them to each other.
No word can have the same letter three times in a row.
Every spoken syllable of a word requires a vowel letter to represent it.
This is why we use the <-es> suffix instead of the <-s> suffix to build the word <packages>. The word <package> uses two syllables, and the word <packages> uses three. Thus we cannot add the suffix <-s>. We need the plural suffix that has a vowel letter so that the new syllable is represented.
Certain letter combinations are not allowed in words of complete English origin, such as:
< uv > and < uu >
Certain letters are not allowed at the end of complete English words, such as:
<i>, <u> — except <you>, and <v>
< j > is not written at the end of a base element or segment; use < ge > instead.
The letter < j > is extremely rare even in the middle of a base element.
Don’t write a double letter at the beginning of a word or base element.
The letter < q > must always be followed by the letter < u > to form the consonantal digraph < qu >
except in <qwerty>. This <u> does not count as a vowel.
