Sense: verb/1
'Invoke' is the most formal of the four, carrying legal or ritual weight — you invoke a law, a principle, or a deity. 'Cite' is more neutral and academic: you cite a source, a study, or a passage without necessarily using it as authority for action. 'Appeal to' is less formal than 'invoke' and emphasises persuasion — you appeal to someone's sense of fairness, whereas you invoke a specific rule. 'Refer to' is the broadest and most everyday option: you can refer to anything from a recipe to a textbook. In practice, choose 'invoke' for formal contexts where you are putting a rule or authority into effect, 'cite' for mentioning evidence in writing, 'appeal to' for trying to persuade, and 'refer to' for simple mentions.

Etymology
The word 'invoke' comes from Latin 'invocare', meaning 'to call upon'. This is formed from 'in-' (into, upon) and 'vocare' (to call). It entered English through Old French 'invoquer' around the 15th century. The original sense was religious — calling upon a god — which then broadened to include calling upon laws, rules, and eventually any kind of summoning.
