Explanation
Focus is the part of an utterance presented as especially informative, contrastive, or relevant to the current question. It does more than assign prominence; it activates alternatives. “MARA found the key” contrasts possible finders, whereas “Mara found the KEY” contrasts possible objects. Languages mark focus through stress, word order, particles, cleft constructions, or combinations of these resources. The same surface sentence may receive different interpretations after different questions. Focus therefore connects sentence form with discourse sequence and assumptions about knowledge. It reveals that information does not possess communicative value in isolation but acquires it relative to possibilities that were open and to the particular alternative selected by an utterance.
Movement of thought
1. A discourse question or expectation establishes a set of possible answers. 2. The utterance selects one element as its decisive new or contrastive contribution. 3. Prosody, position, or construction directs attention toward that element. 4. Substitution tests reveal the activated alternatives and the precise contrast. 5. The sentence returns as a targeted selection within a larger space of possibilities.
Scientific use case
Experiments can vary contextual questions and prosodic accents to measure focus interpretation and processing. Corpus studies can compare how languages mark alternatives through syntax, particles, and intonation.
Example
In response to “Who found the key?”, “MARA found it” places focus on the person. Stress selects Mara against the contextually available set of possible finders.
Counterexample
A loud or typographically conspicuous word is not automatically linguistic focus when it establishes no relevant alternative. Sentence-initial position alone is likewise insufficient without context and information structure.
Distinction
Distinguish focus from topic, accent alone, and general emphasis. Topic supplies a point of departure, while focus is the responsive or contrastive contribution; accent is one possible but insufficient marker.
Effect on thought and perception
Focus concentrates an utterance's communicative energy where it answers an open question or corrects an expected alternative.
Resonance
One form emerges from a field of possible answers; the unselected alternatives remain audible as the background of contrast.

Historical background
Jespersen reviews analyses in which the newly communicated element can occur in different parts of the same sentence. His discussion of a journey distinguishes a previously known traveller, destination, time, or mode of travel from whichever detail the hearer needs. This is an important historical background for focus: prominence is relative to the question and prior understanding, not permanently attached to one grammatical role. The Atlas can use the distinction to explain how stressing a different element changes the alternatives an utterance addresses. Jespersen resists multiplying senses of subject and predicate to describe that effect. His account anticipates a problem later formalised differently, but does not establish every modern definition of focus or the label’s full history.
How conceptual history changes the analysis
Identify the prior question, then change the prominence. The same sentence can address different alternatives depending on what is already known.
