A 'yes' value indicates that the language has reason clauses which are grammatically identical to independent finite clauses. Such clauses may be introduced by a 'reason' conjunction, as in English <i>He sleeps <b>because</b> he's tired</i>, a complex conjunction, as in Icelandic <i>af því að</i> 'because (lit. of it that; Sigurðsson 1981), a clitic marker as in Trumai <i>kawao-k iki-n<b>-ak</b></i> 'wasp-ERG sting-3ABS<b>-because</b>' (Cristofaro 2008), or no overt marker at all, as in Canela-Kraho (Cristofaro 2008).
