For lese the OED has links to leash, lease, leach (obs. thin strips of meat) and the verb leese.

From the definition of the obsolete verb leese:

[A Com. Teut. strong vb.: OE. -léosan, only in compounds, beléosan, forléosan (-léas, -luron, -loren) corresponds to OFris. ur-liasa, OS. far-liosan (Du. ver-liezen), OHG. vir-liosan (MHG. verliesen, mod.G. verlieren, influenced by the pa. tense and pa. pple.), Goth. fra-liusan; other derivatives of the root (*leus-: laus-: los-) are leasing n., -less, loose a. and v., lose v., loss.
The root *leus- is usually regarded as an extension of the *leu-, *lu- in Gr. kÊ-eim, L. so-lv-Sre to loosen.]
