Etymology 2
From, from (verb),  (noun) from , from the same root as, derived from , and thereby related to Etymology 1. The religious sense is presumably introduced in the Gothic church, from 🇨🇬. This semantic development is unique to Gothic, the term glosses Greek, Latin which do not have similar connotations of "holding fast". The feminine noun 🇨🇬 likely existed in the 8th century (shift to neuter 🇨🇬 from the 9th century, whence modern 🇨🇬). The Old English noun originally had the sense "fortress, enclosure" and takes the religious sense only in late Old English, perhaps influenced by. The use for reduced nutrition intake for medical reasons or for weight reduction develops by the mid-1970s, back-formed from the use of the verbal noun in this sense (1960s).

Verb

 * 1)  To practice religious abstinence, especially from food.

 * 1)  To reduce or limit one's nutrition intake for medical or health reasons, to diet.
