A reflexive construction is a construction that can only be used when two °argument positions of a °clause require °coreference and that contains a special form (a °reflexivizer) that signals this coreference.
The definition here is adapted from Haspelmath (2023: 20). It should be noted that a reflexive construction is defined here as a construction-strategy, not in functional terms, so that a clause such as "He shaved" is not reflexive (though it shows agent-patient coreference).
reflexive event (sem) / construction (cxn): an event type in which a participant acts upon themself – that is, the participant is both the initiator and endpoint of trans- mission of force; and the construction expressing such an event. Examples: reflexive events may be direct, when there is no other participant, as in I saw myself; or indirect, when there is another participant in an intermediate position in the causal chain, as in Sally baked a cake for herself, whose causal structure is Sally → cake → Sally.
