Origin and history of loom

early 15c., ayre lome, a hybrid from heir + loom (n.) in its original but now otherwise obsolete sense of "implement, tool," extended to mean "article." Technically, some piece of property that by will or custom passes down with the real estate. General sense of "anything handed down from generation to generation" is from 1610s.

"crippled or disabled by injury to or defect of a limb or limbs," especially "walking with difficulty," Middle English, from Old English lama "crippled, lame; paralytic, weak," from Proto-Germanic *lama- "weak-limbed," literally "broken." This is reconstructed (Watkins) to be from PIE root *lem- "to break; broken," with derivatives meaning "crippled" (source also of Old Church Slavonic lomiti "to break," Lithuanian luomas "lame").

In Middle English especially "crippled in the feet," but also "crippled in the hands; disabled by disease; maimed." The figurative sense of "imperfect, halting, defective in quality or quantity" is attested from late 14c. The sense of "socially awkward" is attested from 1942.

As a noun meaning "crippled persons collectively" it is attested from late Old English. To come by the lame post (17c.-18c.) was an old colloquialism in reference to tardy mails or news out-of-date.

Germanic cognates include Old Norse lami "lame, maimed," Dutch and Old Frisian lam, German lahm "lame."

1794, from hand (n.) + loom (n.).
