What does aspersion mean?
An aspersion is a damaging or slanderous remark, insinuation, or accusation directed at a person's character, reputation, or motives. The word is remarkable for how tightly bound it is to a single expression: English speakers almost always encounter it in the phrase 'to cast aspersions on (or upon) someone', meaning to make unfounded claims that sully their good name. Because of this collocational lock-in, using aspersion outside that phrase can sound unusual or overly literary. The word is distinctly formal in register, appearing more often in journalism, political discourse, and legal contexts than in casual conversation. Its connotation is firmly negative — an aspersion is not merely criticism but a suggestion of wrongdoing, dishonesty, or inferiority, frequently without evidence. Understanding the term is useful precisely because it names a common rhetorical move: attacking credibility through insinuation rather than direct argument.
nounA damaging or derogatory remark or insinuation about someone's character or reputation. It is used almost exclusively in the phrase 'cast aspersions on', meaning to slander or discredit someone.
- A damaging or derogatory remark or insinuation, typically about someone's character or reputation (almost always in 'cast aspersions').
- The act of slandering or defaming someone; a sprinkling of false accusations.
"The senator angrily denied the aspersions cast upon her integrity by the opposition."
"He resented the aspersions his rival had cast on his professional competence."
"Without offering any evidence, she continued casting aspersions on her colleague's motives."
The plural is by far the more common form, since the word typically appears in the fixed phrase 'cast aspersions on'. The singular is grammatical but noticeably rarer.
"She refused to dignify the aspersions with a response."
Aspersion comes from the Latin for 'sprinkling' — so when you cast aspersions, you're literally splattering someone with mud.

Etymology of aspersion
Aspersion derives from the Latin 'aspersio', meaning 'a sprinkling', from 'aspergere' ('to sprinkle'), built on 'ad-' ('toward') and 'spargere' ('to scatter'). The word entered English in the early 16th century, initially carrying its literal sense of sprinkling with liquid (as in baptismal rites). By the late 16th century it had developed its figurative sense of 'sprinkling' someone with slanderous remarks — the metaphor being that slander is flung at a person like splashed water or dirt. It shares its Latin root with related words such as 'disperse' and 'intersperse'.
How aspersion is actually used
Aspersion is formal in register and appears overwhelmingly — nearly exclusively — in the fixed expression 'to cast aspersions on/upon'. Using it outside this construction is rare and may sound stilted. It carries a strongly negative connotation and often implies that the accusation is unjustified or unsubstantiated.
Easily confused with aspersion
Dispersion refers to the scattering of things (light, particles, people), while aspersion refers only to a verbal attack on someone's character.
