In a way that is dull and repetitive, without any variation or excitement.
The teacher spoke monotonously, making it hard for the students to stay awake.
Monotonously → It is formed from "mono-" (from Greek "monos", meaning single or alone) and "tonus" (from Greek, meaning tone or sound) combined with the suffix "-ously" (meaning in a manner). The word "monotonously" describes an action done in a single tone or without variation, often implying dullness or lack of interest.
Think of 'single tone' ('mono-') when you hear 'monotonously' — it helps you remember that it means something done in a dull, unchanging manner.
