Explanation
Language change is the durable alteration of linguistic forms, meanings, rules, or distributions of use through time. It does not arise from one decision alone but as variants are differently acquired, evaluated, and transmitted within communities. Sound change, semantic change, grammaticalisation, and changes in conversational norms need not follow the same mechanism. Synchronic variation may indicate change but is not identical with it; only temporally ordered evidence demonstrates a shift. An individual slip or a short-lived fashion is likewise insufficient. The concept reveals language as a historical configuration: every present form carries earlier choices, contacts, and reanalyses and may become the point of departure for new regularities.
Movement of thought
1. A speech community first uses forms and rules that appear to constitute a present order although they have themselves developed historically. 2. New variants arise through articulation, analogy, contact, acquisition, social positioning, or a changed analysis of an existing pattern. 3. Variants spread unevenly across groups, situations, and generations and may supplement, functionally shift, or displace older forms. 4. A counter-test orders evidence through time and separates durable change from synchronic variation, individual error, deliberate planning, and short-lived fashion. 5. The altered form returns as a new condition of speaking: what was the outcome of earlier processes becomes the ground of changes still to come.
Scientific use case
Historical linguistics and sociolinguistics combine dated texts, corpora, dialect evidence, and generational comparisons. They test mechanisms, diffusion, and intermediate stages rather than merely contrasting before and after forms.
Example
An originally spatial expression increasingly serves as a temporal marker across generations; corpora reveal intermediate stages, competing readings, and eventually a new convention.
Counterexample
One speaker makes a single slip or spells a word unusually. Without social diffusion, temporal stabilisation, or systematic reanalysis, this is not yet language change.
Distinction
Distinguish it from synchronic variation, individual innovation, slips, borrowing as one possible process, etymology as reconstruction, language planning, and normative claims of language decay.
Effect on thought and perception
Language change places differences within historical processes and explains how repeated use can turn variants into new meanings, forms, and grammatical regularities.
Resonance
A small deviation is taken up by others; through many time-shifted responses it thickens into a route that later speakers encounter as already given.

Historical background
Sapir’s account of drift distinguishes variation visible at one time from the historical transformation of a linguistic system. The coexistence of different pronunciations or preferences is not yet an explanation of why a pattern becomes established across generations. He asks how groups that cease moving together can develop different trajectories, and how wider contact can also counteract local divergence. These are explanatory proposals in a 1921 monograph, not proof that every change has one inevitable direction. For the Atlas, the historical importance lies in refusing to treat change as a pile of individual mistakes. What appears irregular from the perspective of one moment may belong to a longer reorganisation of forms and relations. Conversely, a predicted direction must not be confused with a law guaranteeing a future outcome. The chapter documents the English technical discussion of language change through the organising metaphor of drift. Earlier terminology and later competing mechanisms require further evidence beyond this witness.
How conceptual history changes the analysis
A departure is not yet a change. Temporal sequence, social spread and possible systemic reorganisation are decisive.
