Origin & History of “ail”

Now virtually obsolete except in the metaphorical use of its present participial adjective ailing, ail is of long but uncertain history. The Old English verb egl(i)an came from the adjective egle ‘troublesome’, which had related forms in other Germanic languages, such as middle Low German egelen ‘annoy’ and Gothic agls ‘disgraceful’, aglo ‘oppression’. The derivative ailment did not appear until as late as the 18th century.
