What it means
いかにも is an adverb meaning “indeed,” “truly,” or “unmistakably.” It emphasizes that a quality or behavior is strongly apparent, characteristic, or exactly what one would expect. It commonly appears before an adjective or before a predicate containing らしい, and it often conveys “very much like...” rather than a neutral factual “indeed.” The expression is more evaluative and inferential than a simple statement of fact.
Usage note
Do not treat いかにも as a universal intensifier equivalent to “really.” In expressions such as いかにも学者らしい, it means that someone strongly fits the expected image of a scholar. Used alone as a response meaning “indeed,” it can sound formal or literary.
