Question

Why can't you make another word using all the letters in "anagram"?

Answer 1

Because English is a cruel, chaotic language.

Answer 2

Because the rules for vowel combinations does not frequently include 2 'A's let alone 3 of them.

"bit"

add an "e"

"bite"

and you change the wound of the vowel. That is a sample vowel combination rule.  There are very few if any for 2 A's.

Side note the play Managra is an anagram of the word anagram.
