UK[ˈɪp.sə.tɪv]US[ˈɪp.sə.tɪv]
adj

adj
In psychology, describing a type of assessment where a person's responses are compared only within their own set of responses, rather than against a group norm.
Etymology
The term 'ipsative' is a 20th-century creation, primarily used in psychology and education. It is constructed from the Latin pronoun 'ipse', meaning 'self' or 'very', which conveys the concept of intrinsic reference. The suffix '-ative', of Latin origin via French, forms adjectives meaning 'pertaining to'. Therefore, the literal construction yields 'pertaining to the self'. This etymology perfectly captures the modern abstract meaning: a measurement or comparison that is self-referential, where the benchmark is the individual's own previous state or internal set of choices, rather than an external standard. It represents a specialized lexical development to describe a key concept in psychometrics and personalized assessment.
Analysis
The word is a modern scholarly formation, treated as a simplex unit for analysis. It is derived from the Latin pronoun 'ipse' (meaning 'himself, herself, itself') combined with the English adjectival suffix '-ative' (meaning 'of or relating to, tending to'). The core element 'ips-' is taken directly from the Latin stem.
Examples
