ideas for commoner/amateur classes?

in 3rd ed they had rules for commoner classes. so instead of a stat block, you could roll up a character with the class of warrior, which is a fighter who can't hack it as an adventurer.

they just had one for martial, one for arcane, and one for divine; but I was thinking about one per class. not thinking about the specific rules, just thinking of what to name them, and how in lore they would do what they do. for example a shitty cleric, would be an acolyte, and is more about actually providing religious services. shitty warlock is more challenging.

any ideas?
