* Old French: The original form is "anoier," meaning "to be weary, bored, tired, or vexed."
* Latin: This word traces back to the Latin "in odio esse," meaning "to be in hatred."
So, the root meaning of "annoying" is something that makes you feel weary, bored, or even hateful. This meaning has evolved over time to include the modern sense of "irritating" or "bothersome."
Therefore, the word origin of "annoying" ultimately stems from a feeling of being weary or even hateful.
