What does asserter mean?
An asserter is a person who asserts — that is, someone who states a claim, belief, or position firmly and with conviction. The word is formed straightforwardly from the verb "assert" plus the agentive suffix "-er," and it belongs chiefly to formal or literary registers; everyday speech more often reaches for alternatives such as "advocate" or "champion." An asserter can be anyone declaring an opinion emphatically, but the word is especially apt for those who insist on rights or principles: a defender of civil liberties might be described as a steadfast asserter of individual freedom. Because asserting implies confidence bordering on insistence, the noun can carry a subtly forceful, even obstinate coloring depending on context. Its relatives are far more common — "assert," "assertion," "assertive," and "assertiveness" — making the asserter himself or herself a rarer, more deliberate choice of word, one that foregrounds the human agent behind a bold statement.
nounA person who asserts something, especially someone who states a belief, claim, or right firmly and confidently.

"Throughout the trial she remained a firm asserter of her innocence."
"He was a vigorous asserter of the view that good writing cannot be taught."
"As a lifelong asserter of workers' rights, she never shied away from a difficult negotiation."
The plural follows the standard regular pattern; it typically refers to multiple people who insist on similar claims or rights.
"History remembers its great asserters of liberty more vividly than its silent conformists."
English rarely lets you turn 'assert' into a person so cheaply — just add '-er' and you've got an asserter, though most writers reach for 'assertion' instead.

Etymology of asserter
"Asserter" derives from the verb "assert," which entered English in the early 17th century from Latin "adserere" (also written "asserere"), meaning "to lay claim to" or "to affirm," a compound of "ad-" ("toward") and "serere" ("to join or bind together"). The same Latin root "serere" gave rise to a family of English words including "series," "serial," "insert," and "exert." The agent noun "asserter" was formed within English by adding the native suffix "-er" to the borrowed verb.
