Answer :
The best answer is: "- ed is attached before en - BECAUSE - ed is derivational."
This is because "enlisted" is formed by adding the derivational suffix "-ed" to the base verb "enlist" to create the past tense form.
In English morphology, derivational morphemes, like "-ed," alter the meaning or function of a word, while inflectional morphemes, like "-en," typically indicate grammatical features such as tense or plurality without changing the core meaning of the word.
