Amharic

allälä - to be in heat (equines); to desire sex (AED 1102)

Semanically possible, but hard to prove.

PS
*hll - to be imbecile, weak-minded, mad; be mocked at (SED I No. 19ᵥ)
Originally rather a biconsonantal stem. Note various ways of triconsonantization in Eth. and a full reduplication in Arb. and Soq.
