A negative adjective appearing as {(a)láqa >>} alla in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/105 note #67), so probably meaning “✱no” as in alla Elda pole quete “no Elf can say”. It can also be used pronominally to mean “nothing”, and for this function it has a variant lála (PE23/104). For example: merin alla “I want nothing”, or merin alla sino “I want none of this”.
