disc▪ DRS sees ‘croître, grandir, prospérer, être pur, probe’ as one semantic unit but does not explain why/how ‘croître, grandir, prospérer’ should be seen together with ‘être pur, probe’.
▪ The value ‘to grow, increase’ seems to be attested in Ar only. For ‘purity’ (and ‘alms’) which, as an Aramaism, ultimately goes back to Sem *ḎKW/Y rather than to *ZKW/Y, see ↗zakā ↗zakāẗ.
▪ For a discussion of the complex entanglements within the root, see disambiguation entry ↗ZKW/Y.
