Definition / Forklaring
For at gætte om fortiden bruger engelsk modalverber med have + past participle. Strukturen gør det muligt at se bagud og drage en konklusion om, hvad der sandsynligvis skete. Must have viser en stærk positiv deduktion, might have mulighed, og can't have en stærk negativ deduktion. Taleren rapporterer ikke et faktum, men fortolker beviser, resultater eller kontekst. Mønstret er meget almindeligt i samtaler om fejl, tabte muligheder og uforklarede fortidige hændelser.
