disc▪ DRS 10 (2012)#YTM distinguishes 1 ‘orphelin’ from 2 ‘être las, fatigué’ (attested only in Ar).
▪ Cf. in this context also the basic values of YTM in ClassAr as given by Badawi2008: ‘to be one of a kind, to be the best; to become detached; an orphan, weak’.
▪ Given that the value ‘to be detached’ is attested only in Ar while ‘orphan’ clearly is Sem, I tend to see it not as a distinct value (from an etymological perspective) but rather as a semantic extension: ‘to be detached’ = ‘to be as alone and detached as an orphan ’. From the orphan’s isolation it is also easy to imagine the figurative value ‘one of a kind’ to be derived. However, should also the ClassAr value ‘to be tired, unable to continue with s.th.’ be connected to ‘orphan’, or should it be treated, with DRS, as a distinct value? The ‘weakness’ of the orphan could have developed into ‘lassitude, fatigue’… As long as we do not have further evidence there are no decisive answers to these questions.
