Grep search for count of letters beginning with a certain letter

Say I have a text file (allWords.txt), that contains all the words in the dictionary, line by line, that I would like to search through. Here is a snippet of what it might looks like...

a aah aahed aahing aahs aardvark aardvarks aardwolf ab abaci aback abacus abacuses abaft ......

I would like to use the grep search to search, line by line, for all the words beginning with a certain letter and count how many times another letter occurs in that word.

Foe example: I want to search through all the words that begin with the letter "a" and count how many times the letter "e" occurs in that word.

Is that possible.

This is a simple example:
$ grep '^[a]' test | grep e -o | wc -l

$ grep '^[a]' test

$ cat test
