▪ v1 ↗ʕalima, ↗ʕilm ▪ v2BDB#ʕLM-2: perhaps orig. ‘to be mature (sexually)’, Aram ʕᵃlēm ‘to be strong’, Syr ʕālem ‘to rejuvenate’ (certainly denom.), Ar ġalima ‘be lustful’ (denom.), cf. also Sab ʕlm, ʕlmn ‘young man’, Ar ġulām ‘id.’, Phn ʕlmt‑ ‘girl’, Nab Palm ʕlm, ʕlym ‘slave’, Palm f.pl. ‘harlots’, Syr ʕalmā ‘young man’, ʕalmtā ‘young woman’
While the meaning ‘woman of learning, woman scholar’ (v1) is just a PA from the vb. ↗ʕalima ‘to know’, itself probably denom., the value ‘singing girl’, found in EgAr, may be a loan, most probably from Hbr ʕalmā ‘young woman (ripe sexually; maid or newly married)’.1
As such, the word is related etymologically to ↗ĠLM (e.g., ġulām ‘boy, youth, lad; slave; servant, waiter’) rather than to ʕLM.
