What do we call a comment that is repetitive and lacks originality?

The term that describes a comment that is repetitive and lacks originality is "platitude." A platitude refers to a statement that is overused, clichéd, or lacking in depth and thoughtfulness, often presenting a superficial or obvious point that fails to provide new insights. Platitudes can often be found in various contexts, such as conversation, writing, or speeches, where the intent might be to convey a comforting idea, but the result comes off as uninspired or trivial.

Understanding this concept helps recognize when communication may fall flat due to overreliance on common phrases or ideas, which may not add value to a discussion or thought process. In contrast, other terms like "sanction" relate to approval or penalties, "soliloquy" refers to a speech made by a character alone on stage (typically in drama), and "mollify" means to soothe or calm someone’s feelings. None of these terms align with the meaning of a repetitive statement lacking originality.
