| **Definition**: The expression ''(s STRT t)'' states that the temporal beginning of an event ''s'' or the beginning of the validity of a state of affairs ''s'' is determined by the second argument ''t'', which can be another situation, a moment, or a period of time. If the second argument of the expression ''(x STRT y)'' denotes a situation (i.e. ''y ∈ si''), then the temporal beginning of ''x'' is determined by the beginning of that time interval ''ty'' which is attached to the situation ''y'' (''ty'' = time interval of the validity of ''y''). In this case, the duration of ''y'' or ''ty'' must not be longer than that of situation ''x''. The relation ''STRT'' is defined only in those cases where the first argument has a certain duration. See also [[FIN]]. | **Definition**: The expression ''(s STRT t)'' states that the temporal beginning of an event ''s'' or the beginning of the validity of a state of affairs ''s'' is determined by the second argument ''t'', which can be another situation, a moment, or a period of time.
