The connective /f/then is distinguished into EXPANSION.EXEMPLIFICATION, CONTINGENCY.CAUSE.RESULT and CONTIN-GENCY.CAUSE.REASON readings, depending on the lexemes around it, the parents of its arguments, and whether its argument 2 is tensed or not.
nontensed arguments are most often nominalisations leading to a reason reading, whereas a verb phrase as argument 2 and a sentence as argument 1 often is a result reading.
