Explanation
Synonymy is similarity of meaning between distinct expressions whose conditions of use are rarely identical in every respect. Words may designate the same domain yet differ in register, evaluation, collocation, regional distribution, or syntactic behaviour. Substitutability is therefore not a fixed property of a word pair but a relationship to be tested in particular contexts. Even apparently close forms such as begin and start do not always create the same tone or enter the same combinations. The concept redirects attention from abstract sameness to a field of graded alternatives. Synonymy reveals how speakers both refer and position themselves through lexical choice: every variant carries a history, a social location, and a perspectival colouring.
Movement of thought
1. Two expressions initially appear to be different names for the same object, event, or conceptual region. 2. Trial substitution reveals the sentences in which propositional content remains largely stable despite the lexical change. 3. Register, collocation, evaluation, and historical or regional distribution then expose differences within the semantic proximity. 4. A counter-test searches for contexts where substitution becomes ungrammatical, changes stance, or shifts the range of reference. 5. The expressions return not as redundant duplicates but as organised alternatives carrying different resonances and constraints.
Scientific use case
Corpus linguistics and lexicography compare substitution frames, collocations, register labels, and diachronic distributions. Experiments can test whether variants preserve reference while triggering distinct social or affective evaluations.
Example
In “The meeting begins at nine,” begins can be replaced by starts with little change; in “begin a new life,” start remains possible but produces a somewhat different stylistic profile.
Counterexample
Dog and animal may refer to the same creature in a situation, but animal is a superordinate term and cannot be replaced by dog in every context. Shared reference alone is not synonymy.
Distinction
Distinguish synonymy from co-reference, hyponymy, translation equivalence, and mere thematic association. Synonyms need not be interchangeable everywhere, but their semantic proximity must be systematic rather than an accidental sharing of one referent.
Effect on thought and perception
Synonymy enlarges expressive choice and enables fine positioning, whereas a claim of total sameness can conceal consequential differences in use.
Resonance
Near words form a field of tension: attempted substitution makes audible which components of meaning resonate together and which belong to only one variant.

Historical background
The Cours treats neighbouring French expressions for fear as mutually delimiting their values. Within this theory, alternatives contribute to what an expression means. This is a structuralist explanation, not an experiment proving that every substitution changes every context, nor the origin of the older category synonymy.
How conceptual history changes the analysis
Test substitution under specified conditions. State what actually changes in information, stance or expectation.
