An -al at the end of a word indicates a/an

A suffix.

Explanation:

A suffix is a morpheme added to a stem word to form a new word. By adding suffix at the end of a stem word, we are able to form a new word.

For example, the noun word 'account' is used to form a new word 'accountable' by adding suffix '-able'. Similarly, the noun word 'accountant' is formed by adding suffix '-ant' to the stem word 'account.'

In the given question, '-al' is a suffix which refers to an 'act or process of' something. For example, the word 'appraisal' is formed by adding '-al' to the stem word 'appraise.'

So, the correct answer is a suffix.
