Old English ælmesse "alms, almsgiving," from Proto-Germanic *alemosna (source also of Old Saxon alamosna, Old High German alamuosan, Old Norse ölmusa), an early borrowing of Vulgar Latin *alemosyna (source of Old Spanish almosna, Old French almosne, Italian limosina), from Church Latin eleemosyna (Tertullian, 3c.), from Greek eleemosyne "pity, mercy," in Ecclesiastical Greek "charity, alms," from eleemon "compassionate," from eleos "pity, mercy," which is of unknown origin, perhaps imitative of cries for alms. Spelling perversion in Vulgar Latin is perhaps by influence of alimonia.

aloe (n.) Look up aloe at Dictionary.com
Old English alewe "fragrant resin of an East Indian tree," a Biblical usage, from Latin aloe, from Greek aloe, translating Hebrew ahalim (plural, perhaps ultimately from a Dravidian language).

The Greek word probably was chosen for resemblance of sound to the Hebrew, because the Greek and Latin words referred originally to a genus of plants with spiky flowers and bitter juice, used as a purgative drug, a sense which appeared in English late 14c. The word was then misapplied to the American agave plant in 1680s. The "true aloe" consequently is called aloe vera.
